The check digit (last digit) for global trade ID number are calculated by summing the odd position numbers and multiplying by 3, and then adding the sum of the even position numbers. The final digit of the result is subtracted from 10 to calculate the check digit (or left as is if already zero).

The error is caused because the GTIN you supplied is not in adherence to the above calculation.

Maintain the GTIN with check digit as per the above mentioned calculation. If you need an example to understand the calculation better, you can find it on the official GS1 website:
