So, in order to verify the authenticity of the barcode should do the simple math. For example, such bar code: 4005808158003.Check that only digits 13. The last digit 3 – test.
Sum the digits in the even positions, i.e., fold each of the second, fourth, sixth, etc.
0+5+0+1+8+0=14
Multiply the total by 3. It is a formula it cannot be changed. 14*3=42
To the above add the product of the numbers at odd places.
42+4+0+8+8+5+0=67
From 10 (always 10) subtract the last digit of the sum. 10-7=3
Check it with the check digit. 3=3.
The bar code is genuine, and, hence, the quality of goods can be trusted.
