As we are at the moment verifying all fields against the CAS commonchemistry.org site, the bot replaces XXX with 'CAS' (i.e., <code>{{<a href="/wiki/Template:Cascite" title="Template:Cascite">cascite</a>|correct|CAS}}</code>). When using another place to verify the CASNo, please adapt this parameter accordingly and will try to retain this field throughout. When there will be significantly more verifications against non-commonchemistry.org-places, I will instruct the bot to fill the field standard with <code>{{<a href="/wiki/Template:Cascite" title="Template:Cascite">cascite</a>|correct|??}}</code> or something similar. </p> <div class="mw-heading mw-heading2 ext-discussiontools-init-section"><h2 id="Method_of_work" data-mw-thread-id="h-Method_of_work"><span data-mw-comment-start="" id="h-Method_of_work"></span>Method of work<span data-mw-comment-end="h-Method_of_work"></span></h2></div> <p>Our approach is to start by checking that the CAS registry number and the structure match with the name. This will be used as a foundation upon which we can build a broader validation effort. Once we have the structure verified, we have the formula, and hence the molar mass, and we can also generate other machine representations such as SMILES, InChI and InChIKey. </p> <div class="mw-heading mw-heading3"><h3 id="First_1000" data-mw-thread-id="h-First_1000-Method_of_work"><span data-mw-comment-start="" id="h-First_1000-Method_of_work"></span>First 1000<span data-mw-comment-end="h-First_1000-Method_of_work"></span></h3></div> <p>After our <a href="/wiki/Wikipedia:WikiProject_Chemistry/IRC_discussions" title="Wikipedia:WikiProject Chemistry/IRC discussions">IRC meeting on January 13, 2009</a>, we used an Excel file to validate the first 1000 entries from the CAS XML file.

There would be another four CAS#s for the hydrochloride, four for the (1:1) sulfate, four for the (2:1)sulfate, etc. It is very important that we match the correct form CAS# to our Chemboxes!</li> <li>Be aware that CAS uses an unusual system for representing some formulae, which may seem "wrong" to us. These involve describing salts such as sodium nitrate as HNO<sub>3</sub>·Na, and organic salts follow a similar system. Do not use such formulae on WP, but they are not "wrong" since they are merely a representation, not a formal structure. This also results in incorrect MolarMass in the FW section of the SDF file for salts.</li> <li>For complex chiral structures, such as <a href="/wiki/Bleomycin" title="Bleomycin">bleomycin</a>, which may be drawn very differently in WP than in Common Chemistry, I found it best to assign R/S for each center and compare that way.

Neither compound has the stereochemistry correctly specified. <ul><li>I've rechecked Dieldrin, adding the implicit hydrogens to the WP structure and drawing in chemsketch, I also copied the CAS structure exactly and had the program assign stereo labels. They match, which leads me to think my initial verify is OK. It maybe should be noted that while the carbon skeletons look to be the same projection, WP is from above and CAS (turns out to be) from below. If you are still unhappy could you describe your assignment in more detail?

There is an older version of this image <a class="external text" href="https://upload.wikimedia.org/wikipedia/commons/archive/7/7a/20060104083339!Endrin.png">Endrin.png</a> and this does match. Given the difficulties of transposing a 3D structure to more conventional form it would probably be better to have a more conventional structure as well for compounds like this but I would suggest we avoid removing 3D structures providing it is possible to validate them. I will investigate further. <ul><li>I suggest that for our <a href="https://commons.wikimedia.org/wiki/Commons:WikiProject_Chemistry/Structure_validation" class="extiw" title="commons:Commons:WikiProject Chemistry/Structure validation"><i>validated</i> structure</a> on such compounds, we should explicitly show the stereochemistry of each chiral centre, which is not the case at present on Endrin and Dieldrin (even if a knowledgeable chemist can figure out what it <i>must</i> be from the diagram). That doesn't <i>necessarily</i> mean changing the structures in the chemboxes (our images for inorganics don't always give a clear idea of the structure), but we should insist on the chembox information being correct and not-misleading, and that the full details be available in the article (maybe in a separate image). <a href="/wiki/User:Physchim62" title="User:Physchim62">Physchim62</a>
