Exact Image's bardecode does not provide it, but you can easily calculate that character: https://en.wikipedia.org/wiki/EAN-13

Thank you. I solved this problem.

No problem. You can share your code here if you like ;)

function calculateBarcodeWithChecksum(barcode) {
            var no = barcode;
            var sequence_ean13= [1,3];
            var sums = 0;

            var no_array = no.split("");

            for (var i = 0; i < no_array.length; i++) {
                   sums += no_array[i] *  sequence_ean13[i % 2];
            }

            var checksum = 10 - (sums % 10);
            if(checksum == 10){
            checksum = 0;
            }
            var ean_code = no+checksum;
            return ean_code;
}
