What is a check digit on a barcode?
A check digit, also known as a checksum character, is the number located on the far right side of a bar code. The purpose of a check digit is to verify that the information on the barcode has been entered correctly.
How is GTIN 14 check digit calculated?
- GTIN-8.
- GTIN-12.
- GTIN-13.
- GTIN-14.
- SSCC.
- STEP 1: Multiply value of each position by.
- STEP 2: Add results together to create sum.
- STEP 3: Subtract the sum from the nearest equal or higher multiple of ten = CHECK DIGIT.
How do you verify a check digit?
Add the even number digits: 1+1+1+1+1=5. Add the two results together: 0 + 5 = 5. To calculate the check digit, take the remainder of (5 / 10), which is also known as (5 modulo 10), and if not 0, subtract from 10: i.e. (5 / 10) = 0 remainder 5; (10 – 5) = 5. Therefore, the check digit x value is 5.
What is the difference between Code 128 and EAN 128?

How is check digit mod 10 calculated?
The algorithm for calculating a Mod 10 check digit is as follows:
- Using the number 12345, assign positions to the digits, from right to left.
- Take the odd digit positions counting from the right (1st, 3rd, 5th, etc.).
- Multiply by 2.
- Take the even digit positions starting from the right (2nd, 4th, etc.).
