With this autonumber you can use a "modulo 11" routine to generate a checkdigit for printing on your labels.

The modulo is calculated by multiplying the digits with different values and calculating the remainder.

This text from the web shows how:

==========================

In this example, we want to encode the data "21435" in a Code 11 barcode with a single check digit. The check digit is a modulo 11 checksum.

First, we determine the weights of the numbers in the Code 11 barcode starting from the right side of the number. We then multiply the number of the barcode by the weighting and add these together as in the example:

Barcode to encode: 2 1 4 3 5

Weighting: 5 4 3 2 1

Totals: 10 4 12 6 5 Then add them 10+4+12+6+5=37

Next we divide the total by 11 and get the remainder which is 37/11=3 remainder 4. The remainder is the check character.

To type or print a Code 11 barcode encoding the data 21435 that can be scanned, we need to print (214354) .

==========================

This is used on barcodes, but also for your banking number.
