How to Manually Calculate Checksum for Code 128 or GS1-128

I am trying to generate a GS1-128 barcode string and I am having the issues with the check digit. I am producing GS1-128, so my barcode has combination of subsets B and C. I have tried to calculate the check digit based on calculations given in some websites, but I am not getting correct check digit.

Below mentioned are the examples of my barcodes:

40327641468+99000952123001
40327605999+99000900000000

Example of combination of subsets: Start C FCN1 '4032764146' Set B '8+' Set C '9900095212300'

Can you tell me how to calculate the check digit manually?

Best Answer

The recommendation is to use the Code 128 Barcode Font Package or the GS1-128 Barcode Font Suite, use the Code 128 Auto function*, and use the mod10 functionality.

We additionally have other resources for clients:
Manual Mod10 Calculation
Mod10 Calculation VB Example

*Does not have a, b, or c in the name. Check availability in the respective font encoder.

Support Note: IDAutomation only provides support for its encoding and mod10 check calculations.
