Add a gtin (Global_Trade_Item_Number formerly called EAN Number) validator

[Er4twXz]

What type of request is this?

New tool idea

Clear and concise description of the feature you are proposing

I should be easy to add a gtin validator. A gtin is a unique identifier for products. The code can be easily generated by AI using

npm install gtin-validator

https://en.wikipedia.org/wiki/Global_Trade_Item_Number

also there could be a tool to generate the check digit from the 12 digit number

Is their example of this tool in the wild?

Global_Trade_Item_Number

Hi @Er4twXz , implemented here: https://sharevb-it-tools.vercel.app/gtin-validator (and many barcode tools)

And if you are interested in an up to date version of it-tools, with many improvements, new tools, and bug fixes, as this repo is almost no more maintained, I made a fork here : https://github.com/sharevb/it-tools (https://sharevb-it-tools.vercel.app/ and docker images https://github.com/sharevb/it-tools/pkgs/container/it-tools)
