Barcode is the one which represent the data/object by using numbers and lines.The numbers underneath the barcodes are: country’s code, manufacturer’s code, product code and a check digit. Below are the method to find the check digit.

1 3 5 7 9 11 (odd position numbers)

5 1 0 4 3 1 1 2 0 1 7

2 4 6 8 10 (even position numbers)

Total odd:

5+0+3+1+0+7 = 16

Multiply by 3

16x3 = 48

Total even:

1+4+1+2+1 = 9

TOTAL=57

Check digit= 60(nearest whole number by 10)-57 = 3

Thus, the check digit is 3.

The final code will then be:

5 1 0 4 3 1 1 2 0 1 7 3
