RE: Mod 10 check digit calculation

Maybe if you said MODULUS instead of MOD, people would realize that you mean
Modulus in instead of "mod" which means "remainder"

Hi Michael
Mod 10 check digit calculation is where you start with a number, lets say
1234567890. Each of the digits is then multiplied by either 1 or 2
depending upon its position, with the low-end position being multiplied by
2, then the next position to the left, being multiplied by 1, then the next
position to the left, being multiplied by 2,  then the next position to the
left, being multiplied by 1, etc.
For this example 1234567890 becomes
1 x 1 = 1
2 x 2 = 4
3 x 1 = 3
4 x 2 = 8
5 x 1 = 5
6 x 2 = 12
7 x 1 = 7
8 x 2 = 16
9 x 1 = 9
0 x 2 = 0
These answers are then accumulated, in this instance 1 + 4 + 3 + 8 + 5 + 12
+ 7 + 16 + 9 + 0 = 65
The last digit of this answer (5 of 65) is then subtracted from 10, giving
the answer 5
Therefore the check digit for the number 1234567890 is 5
This is how the check digit for a bank account number is calculated.

I quickly wrote this down, and I'm pretty sure this is the correct way to
do the Mod 10 check digit calculation.

Again, if anyone can help, much appreciated

You want a mod 10 calculation of a number right?


11 mod 10 = 1

%Rem(11:10) = 1

Am I missing something?
