stdnum.isin¶
ISIN (International Securities Identification Number).
The ISIN is a 12-character alpha-numerical code specified in ISO 6166 used to identify exchange listed securities such as bonds, commercial paper, stocks and warrants. The number is formed of a two-letter country code, a nine character national security identifier and a single check digit.
This module does not currently separately validate the embedded national security identifier part (e.g. when it is a CUSIP).
