Quick K Calculator

A program is available which calculates the mod 37,2 check character required for keyboard entry of some ISBT 128 data structures in order to verify the accuracy of the input. This is the Quick K Calculator program made available to ICCBBA by Larry Cullen, to whom ICCBBA would like to express its gratitude. ICCBBA makes no warranty concerning the use of this program.

As you enter characters into the white box, the mod 37,2 value will appear to the right.

To find a Donation Identification Number check character, simply enter the thirteen (13)-character data string (i.e., excluding flag characters).
