InChI Lookup

The idea is to create a mechanism that would allow CrossRef publishers to record InChIs in their submitted CrossRef metadata. This, in turn, would allow us to provide a service that would allow users to:

  • Lookup the published articles that mention a particular InChI.
  • Lookup the InChIs mentioned in a published article.

Similar services could, conceivably, be provided for other types of semantic metadata.

The following is a demonstrator of what an DOI2InChI lookup service might look like. Please note that the XML representation of the results is very basic and is not best-practice for linked-data.

The demonstrator currently only holds DOIs and InChIs for a few publishers. A summary of the contents of the database can be found on the status page

A list of all the CrossRef DOIs that contain InChIs can be seen here:

A list of all the InChIs that have been registered with CrossRef can be seen here:

The system provides the following API calls:

Return all the DOIs that have been registered with a given InChI,1H2,2H3

Return all the InChIs that have been registered for a given DOI
