The IUPAC International Chemical Identifier (InChI, see MIR:00000383) is an identifier for chemical substances, and is derived solely from a structural representation of that substance. Since these can be quite unwieldly, particularly for web use, the InChIKey was developed. These are of a fixed length (25 character) and were created as a condensed, more web friendly, digital representation of the InChI.
inchikey
Local identifiers in InChIKey should match this
regular expression:
^[A-Z]{14}\-[A-Z]{10}(\-[A-Z])$
Compact URIs (CURIEs) constructed from InChIKey should match
this regular expression:
^inchikey:[A-Z]{14}\-[A-Z]{10}(\-[A-Z])$

Providers are various services that resolve CURIEs to URLs. The example CURIE
inchikey:RYYVLZVUVIJVGH-UHFFFAOYSA-N
is used to demonstrate the provides available for
inchikey
. Generation of OLS and BioPortal URLs requires additional programmatic
logic beyond string formatting.
Additional providers curated in the Bioregistry are listed here.
