WebInChIKey is a fixed-length format directly derived from InChI. It is based on a strong hash (SHA-256 algorithm) of an InChI string. Because of the hash nature of the InChIKey, there is no guarantee that two distinct molecules will have different InChIKeys. At the time or writing of this article no such collisions are. WebThe converter is an experimental research tool. Please, before using it and complaining about it, read this information about the features and limitations of the converter..
