Hello Josep.

This is not a OutSystems question.

You can use any validator of GTIN-13  or GS1's official one.

The formula is simple: "check digits are calculated by summing the even position numbers and multiplying by 3 and then by adding the sum of the odd position numbers " so you can do it in OS.

I know the GTIN qestion is not outsystems. 

Ans I know the GS1 way of calculating. 

But how can I make such a complex validation myself in OutSystems?
