, you can select the following rule when you add the Core accelerator to a Model repository project:
rule_GTIN_Validation
Validates a Global Trade Item Number (GTIN). The rule validates eight-dight, twelve-digit, thirteen-digit, and fourteen-digit numbers. The rule returns "Valid" if the check digit is correct for the number and "Invalid" if the check digit is incorrect.
