Procedure to obtain the differentiating key of homonymy

1.- Values ​​will be assigned to the letters of the name or company name according to the table of Annex 1.
Example:
Gómez Díaz Emma
G = 17        espacio = 00       espacio = 00
O = 26 D = 14 E = 15
M = 24 I = 19 M = 24
E = 15 A = 11 M = 24
Z = 39 Z = 39 A = 11
NOTE: no special characters should be allowed in the name, except for the "&".
2.- The values ​​are ordered as follows:
G O M E Z   D I A Z   E M M A
017 26 24 15 39 00 14 19 11 39 00 15 24 24 11
A zero is added to the value of the first letter to standardize the criteria for taking numbers two at a time.
3. The multiplications of the numbers taken two at a time will be performed for the position of the pair:
01 * 1 = 1        90 * 0 = 0        90 * 0 = 0
17 * 7 = 119   00 * 0 = 0   00 * 0 = 0
72 * 2 = 144   01 * 1 = 1   01 * 1 = 1
26 * 6 = 156   14 * 4 = 56   15 * 5 = 75
62 * 2 = 124   41 * 1 = 41   52 * 2 = 104
24 * 4 = 96   19 * 9 = 171   24 * 4 = 96
41 * 1 = 41   91 * 1 = 91   42 * 2 = 84
15 * 5 = 75   11 * 1 = 11   24 * 4 = 96
53 * 3 = 159   13 * 3 = 39   41 * 1 = 41
39 * 9 = 351   39 * 9 = 351   11 * 1 = 11
4.- The results of the multiplications are added together, and from the result obtained, the last three digits are taken and divided by the factor 34, for example:
The result of the sum of the multiplications is:
2535
    _15__ cociente
34|535
     195
       25 residuo
5. The quotient and remainder are used to consult the table of Annex 2. and the homonymy is assigned.
Obtaining:
15 = G
25 = R

Therefore, homonymy will be “ GR ”.
