This online tool generates a 1-dimensional barcode symbol (UPC-A) representing 11 input digits.
3 | 1 | 4 | 1 | 5 | 9 | 2 | 6 | 5 | 3 | 5 | 8 | |
×3 | ×1 | ×3 | ×1 | ×3 | ×1 | ×3 | ×1 | ×3 | ×1 | ×3 | ×1 | |

9 | + 1 | + 12 | + 1 | + 15 | + 9 | + 6 | + 6 | + 15 | + 3 | + 15 | + 8 | = 100 ≡ 0 mod 10 |
Any wrong digit and many other digit errors will be detected if the check calculation does not give a zero result. The identical algorithm is used to compute the ISBN-13 check digit.
