Real GTIN Validator
, (*1)
A GTIN is a string of digits that uniquely identifies a trade item (a product that is bought and sold).
A GTIN is globally unique, meaning that no two products in the world share the same GTIN., (*2)
This library provides a straightforward way by which a number can be determined to be a valid GTIN
or suspected of being invalid in some way., (*3)
