WebIt is a tool to be used in software applications designed and developed by those who choose to use it. The InChI algorithm turns chemical structures into machine-readable strings of information. InChIs are unique to the compound they describe and can encode absolute stereochemistry making chemicals and chemistry machine-readable and discoverable. WebMay 7, 2024 · There are currently six InChI layer types, each different class of structural information: the main layer, a charge layer, a stereochemical layer, an isotopic layer, a fixed-H layer and a reconnected layer. The main layer, which specifies chemical formula, atoms, and bonds between them, is required for all InChIs.

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 WebJan 24, 2013 · InChI is the older standard of compound representation introduced by IUPAC.
