Don't know much about this, but here is the algorithm
Add the digits in the odd-numbered positions (first, third, fifth, etc.) together and multiply the total by three:
(7 + 4 + 4 + 0 + 8 + 5) X 3 = (28) x 3 = ( 84)
Add the digits in the even-numbered positions (second, fourth, sixth, etc.).
(1 + 0 + 3 + 3 + 8) = (15)
Add the two results together:
84 + 15 = 99
Now what single digit number makes the total a multiple of 10? That’s the check digit.
99 + 1
1 is the check digit. The full UPC number is now 714043038851
+129850 It's concerning the UPC (Universal Product Code) label found on most items in a grocery store....(also known as a "bar code" )........the bar code is scanned at the register for the price...I think the "check digit" is used to detect fraud....
I'm sure that Australia probably uses some form of this
