isCIFWellFormed

public static boolean isCIFWellFormed(String CIF)

CIF VALIDATION.
1) First letter can be: A, B, C, D, E, F, G, H, N, P, Q, S, J ,U ,V, W, R.
A - Public corporation / Public limited company
B - Limited corporation / Limited company
C - Association / Collective corporation
D - Partnership
E - Co - ownership
F - Cooperatives
G - Associations and other not defined types
H - Home owners associations
J - Civil corporations
U - Temporal companies association
V - Not defined types
N - Foreign entity
W - Permanent establishment of non-resident entity in Spanish territory
Q - Public corporations
R - Religious corporations S - State and autonomous regions administration organisms
P - Local corporations

2) Validation algorithm
1 - Remove the first and the last character in the CIF (first letter and control character), this return a string with 7 digits.
2- Sum all digits in even position, getting a result whose name will be A
3- For each digit in a odd position multiply it by 2, sum the result digits and store this value whose name will be B.
4- Sum A and B getting the result C.
5 - Get the units digit of C and subtract it from 10 (10 - C units digit) getting D.
6 - Using this result D is possible to obtain the control character. If control character must be a numeric value, this is directly D. If control character must be a letter the equivalence is 1-->A, 1 -->B etc.

EXAMPLE: CIF: "A58818501"
Remove first and last character getting "5881854"
Sum the even digits: A = 8 + 1 + 5 = 14
With the odd positions multiply by 2 and sum the result digits:
5 * 2 = 10 ==> 1 + 0 = 1
8 * 2 = 16 ==> 1 + 6 = 7
8 * 2 = 16 ==> 1 + 6 = 7
0 * 2 = 0 ==> 0
B = 1 + 7 + 7 = 15
C = A + B = 14 + 15 = 29
The units digit of C is 9. Abstract this value from 10 getting 10 - 9 = 1
If control character is a letter this is "A". If must be a number is directly 1.
In this example CIF values starts with C and all CIF with C uses a numeric control character.
In case of result = 10 - 0, the validation number will be ZERO or the letter J

Parameters:

CIF -
