The check digit control character is that character, as this last number to the right of a barcode (bar code) needed to validate the reading.
The calculation procedure is quite simple
- 3 Multiply all the numbers in the odd positions (starting from right) and add them together (value A)
- Add all the numbers in the even positions (from right), (B value)
- The control code is obtained by subtracting the ten top of the total sum (A + B) the same sum (eg A + B = 114, the check is 120-114 = 6)

Yes, 13 characters (including check) for EAN13, if you download the sample in Excel format, which was the main part of the article, you'll see that there are 13 including the check digit. Your provider and change the image to avoid possible misunderstandings, thanks for the tip.

you could put this calculation into a function of the barcode so that it can control the exact type of a barcode in a cell of a page work?
Thanks

Hello Peter,
certainly if you download the Excel file for example is easy enough to create what you ask for a few changes. Just compare the last digit of the cell where you type with the check digit created by the formula.

First you have the bar code without check digit (the one you posted I think it is a product key, certainly not a bar code so you do not do anything), then in Excel you can generate the check digit.
If barcodes are to be used to market products to be purchased (Indicod-Ecr).
