2) A single compound must have a single identifier, regardless how its structure is drawn. This second requirement involves the elimination of features of the chemical structure that depend only the way that it was drawn.
The objective of this project is to develop a set of rules (algorithms) for deriving a chemical identifier (sequence of bytes) for a chemical substance based on its chemical structure. This identifier must have two key properties:
1) Different compounds must have different identifiers. To satisfy the first requirement it is necessary to include all chemical features necessary to distinguish one compound from another.
