Redirecting

If you know the identifier, then Scholia can make a lookup based on the identifier:

pubchem/14123361
Look up PubChem CID 14123361. This will identify tetra-tert-butylmethane and redirect to its Scholia page.
cas/50-00-0
Look up CAS 50-00-0. This will identify formaldehyde and redirect to its Scholia page.
inchikey/QTBSBXVTEAMEQO-UHFFFAOYSA-N
Redirect also works for InChIKeys, here for acetic acid.
lipidmaps/LMFA00000007
And for LIPID MAPS identifiers

ChemCuration

There is always more information about chemicals that can be added. This section adds some useful resource for chemistry curation:

PubChem CID violations
This page shows CIDs linked to more than one Wikidata item (a "Unique value" violation) and Wikidata items with more than one CID ("Single value" violations).
Curation of physicochemical properties
This page shows lists of compounds with missing or incomplete information regarding propephysicochemical properties, like boiling points.
