WebInChIKey checker. The last character of an InChIKey is computed from the rest of the InChIKey and can be used to determine if the key wasn’t unintentionally changed during transmission. Using our online service, you can easily check if an InChIKey is valid – the last character matches the rest of the key. Enter your InChIKey below: WebStill, InChIKey inherits from InChI, to a limited degree, a layered representation of chemical structure. InChIKey provides a nearly unique short representation of the parent InChI and hence of the parent chemical compound (the chances of InChIKey non-uniqueness are not zero but rather small, see Section 13 ‘InChIKey’ of this FAQ).
