/**
 * Class Ismn for International Standard Music Number or ISMN (ISO 10957)
 * From 1 January 2008 the ISMN was defined as a thirteen digit identifier beginning 979-0 where the zero replaced M
 * in the old-style number. The resulting number is identical with its EAN-13 number as encoded in the item's barcode.

It seems like you call parent on a different method (check() instead of validate()). Are you sure this is correct? If so, you might want to change this to $this->check().
