The following is a list of Wikipedia articles about inorganic chemical substances, prepared for the CAS validation exercise: as of 2008-03-26, there were 1889 entries.

There is another list, which consists mainly of organics with a few inorganics.

Criteria for inclusion

The main criteria for inclusion is that he substance cannot be easily described by an InChI or by similar systems of connection mapping. This applies to all non-molecular substances and most organometallics and transition metal complexes. Some molecular compounds of the non-metals (eg silicon tetrachloride) have also been included, as it would seem strange to leave them off a list of inorganics.

Excluded articles

  • Proteins, enzymes, DNA structures: see glutathione peroxidase for an excellent example of identifying proteins which doesn't use CAS Registry Numbers.
  • Minerals.
  • Polymers.
  • Heteroorganic compounds, that is, compounds which have a few heteroatoms in an organic compounds and which can be satisfactorily described by InChIs.
  • most "Materials".
  • Substances of unknown composition, eg aphronitre.

Included articles

  • Allotropes of carbon, and other structural modifications which have their own articles, eg the various forms of ice.
  • Specific grades of pure chemicals where these have their own articles, eg dishwasher salt. Some "materials" have been included under this header.
  • Pigments.
  • various Mixtures, so long as we have some information about their chemical composition, including:
    • medicinal and iatrochemical compositions;
    • alchemical substances;
    • alloys;
    • other homogeneous materials of defined composition.

Criteria of classification

This list has been split into element categories. obviously any chemical compound, by definition, could go into more than one element category: categories have been assigned here in an attempt to ensure that the lengths of the various sections are not too disparate.

What needs doing?

We are working on the assumption that the CAS Registry Numbers for inorganic substances will have to be verified against their names, one by one (for organics, the process should be slightly more automated), and we're still not sure exactly what format the list will take.

As a first step, this list needs to be checked for completeness, and we need to know which articles cover more than one substance (eg, mixtures, hydrates, etc).
