Algorithm for Verifying Digit Rut-Id (Chile)

Methods for calculating the digit trier of Chilean RUT/ID/DNI.

The algorithm to validate a rut is easy, write down the rut then each digit is multiplied by the following series of numbers (3,2,7,6,5,4,3,2):

For example:

RUT: 33444111-3

3 x 3 = 9 3 x 3 = 9

3 x 2= 6 3 x 2 = 6

4 x 7 = 28 4 x 7 = 28

4 x 6 = 24 4 x 6 = 24

4 x 5 = 20 4 x 5 = 20

1 x 4 = 4 1 x 4 = 4

1 x 3 = 3 1 x 3 = 3

1 x 2 = 2 1 x 2 = 2

Add it all and gives us: 96

The number you gave us, so we divide by 11 and get the rest (%)

96% 11 = 8

and the last digit verifier is:

11-8 = 3

so the rut is: 33444111-3

Now if the rest is 10, the digit verifier is K

this is the trick to calculate RUT final number in chile :)

good luck!

    Hello.

    I believe that you should add:

    If sum above is divisible by 11 (so 11 – remainder = 11) than control figure should be 0.
