ISIN (International Securities Identifying Number) validation.
ISIN Numbers are 12 character alphanumeric codes used to identify Securities.

ISINs consist of two alphabetic characters, which are the ISO 3166-1 alpha-2 code for the issuing country, nine alphanumeric characters (the National Securities Identifying Number, or NSIN, which identifies the security), and one numerical check digit. They are 12 characters in length.
