Interpret the string as a decimal integer and compute the remainder of that number on division by 97.Replace each letter in the string with two digits, thereby expanding the string, where A=10, B=11.Move the four initial characters to the end of the string.Check that the total IBAN length is correct as per the country.

The checksum is a basic ISO 7064 mod 97-10 calculation where the remainder must equal 1. IBAN is described as follows in its Wikipedia entry: Using the same code, I also created a custom Excel worksheet function as an Automation Add-in and a SmartTag for Word using VSTO. As I needed this algorithm in C#, I developed a C# version from the information presented in these sites. I also found a very good JavaScript example on the UN CEFACT TBG5 website.
I searched the web for check digit calculation, and found it in the IBAN Wikipedia entry.
