"""Compound list for the spectral template library.

Each row: (substance_id, English name, Chinese name, CAS, class).  CAS numbers are the lookup key for both the
NIST WebBook (C-number = CAS without dashes) and PubChem; ``fetch_sources.py`` cross-checks the molecular formula
returned by both services so a wrong CAS is caught before it enters the library.
