WebAug 11, 2024 · The hash function generates a standard key of 27 characters that stores information in four parts (see figure 5). The InChIKey may be a standard or nonstandard key as indicated by the version, but all keys are of the same length and format. Figure \(\PageIndex{5}\): InChI key for 2-(35 Cl)chloro-R-glycine (molecule in figure 1).
