LUHN-10 Error Detection Tool

Error control codes can be implemented within written values such as account numbers and price tags by appending a single check digit according to the LUHN-10 Algorithm.

This particular algorithm is part of a standard (ISO-7812-1) used worldwide for various credit cards. (Specific Applications)

  8 + 4 + 8 + 0 + 0 + 7 + 4 + 1 + 8 + 5 + 8 + 5 + 2 + 9 + 2 + 9  = 80

80 ≡ 0 (mod 10)

The test PASSED since the result is zero.

There is a one-in-ten chance that a totally random number will pass this simple validity test.

Check a LUHN-10 coded number by entering it in the box below. Spaces may be used as desired.
