WebJun 11, 2024 · SMILES doesn't define a particular order in which the atoms show up in the string. Hence the position in the molecule where software starts printing will determine the string. E.g. for CO2: Ketcher prints C (=O)=O (starts with C and considers one of the O's a branch) MarvinJS prints O=C=O (starts iteration with O, hence no branching) WebIt uses a BASE26 alphabet (Hexavigesimal)! // "The InChIKey is a character signature based on a hash code of the InChI string. Also, this hash. // may serve as a checksum for verifying InChI, for example, after transmission over a network." // presence of fixed-H layer); a 1 character is a “check” character.
