check-digit-EAN13 0.1

A simple library to get check digit

Get check digit number of your EAN-13 Barcode.

Here I’m presenting a package to find check digit (system generated digit) of 12 digit number which is used to create EAN-13 Barcode. When we used to create a barcode, the last digit always generated by our machine.In most of the cases, barcode number want to be unique and it is difficult to find if our new barcode number is already existing in our database without knowing this system generated digit and unfortunately I didn’t find any package to find this. That’s why I came accross to build a package to fing this crazy digit.
