The InChI Resolver provides online access to a series of tools supporting the generation and look-up of InChIStrings and InChIKeys.

InChI Generation: Convert SMILEs, load or draw chemical structures and convert to InChIStrings and InChIKeys.

InChI Resolver: Input InChIString or InChIKey and lookup the associated chemical structure.

Web Services: Integrate to our web services to perform InChI Generation and Lookup.

Configurations: Learn about the versions of InChI supported by the resolver.
