InChI Certification Suite

The InChI certification suite is a software package developed and designed to check that your installation of the InChI program has been performed correctly. The programs test your installation against a broad set of structures (which are provided with the Suite).

Once the programs are run and the results sent back to the Trust, an “InChI certified” logo will be sent to the respective person or organization. The InChI Trust certification logo can then be put on the pages of the web site for all users to see. The use of the InChI Trust certification logo is optional.

The cost of the certification suite is US $5000 per year. It can be purchased from the InChI Trust, please contact
