In general, the IUPAC identifier will be created from the input structure in 3 steps:
3. Serialization - converting the canonical set of labels to predictable a string of characters.
2. Canonicalization - labeling atoms using a method that generates the same set of labels regardless how the structure was initially drawn.
1. Normalization - removal of unnecessary information for layer construction.
Most of the ‘chemistry’ involved in creating the IChI is expressed in normalization step.
