CAS registry number validation results based on the following idea:

  • CAS numbers are validated against the 2021 CAS Common Chemistry databases, based on InChIKey match
  • validated numbers are detected on Wikipedia using a substring match

Therefore, a missing can have multiple reasons. The "category" pages likely will have to be solved; the missing CAS number on Wikipedia here reflects that the Wikidata and Wikipedia pages reflect different things: particularly, the sitelink is likely wrong.

Curation Feedback

The below expectations may be incorrect. If you analyzed the situation and the given CAS is not correct for the Wikipedia entry, the following could be the case:

  1. the Wikipedia-Wikidata sitelink is incorrect (e.g. stereochemistry mismatch)
  2. the InChIKey used for the match is incorrect.

Please report these things below under 'Curation notes' which I will monitor.

89022 validated CAS registry numbers in Wikidata linked to Wikipedia pages (https://w.wiki/3A88).

8115 CAS registry numbers in Wikipedia match Wikidata and CAS Common Chemistry. 430 do not, below.

Therefore, current estimate is: at least 95.0% is correct.
