Warwick Identification Number

Warwick Identification Number is an identification system for fictional characters who were willing to be dressed as either Gnomeo or Juliet. Before the Halloween, the character must apply for Warwick Identification Number, generated by a computer, before dressing as either Gnomeo or Juliet depending on the character's gender. The valid characters in Warwick Idenitfication Number are numbers 0 to 9 and letters of the English alphabet.

Format
The format that the Warwick Identification Number uses the form of (II)I/DDMMYYCXNNN/AAA Q, where (II)I represent between one initial and three initials, DDMMYY indicate the date of first appearance, C indicates century, X indicates gender, NNN are random letters or numbers, AAA indicates the age and Q is a check character, which is used to verify whether the Warwick Identification Number is correct or not, and it is usually overlined.

In identity cards, it uses this format:

The sign for the century is either ' (18th century), + (19th century), - (20th century) or A (21st century). To indicate gender, M is used for male, and F is used for female.

AAA denotes the age, if the character's age is either unknown or unconfirmed, it is replaced by XXX.

Q is a check character (and is overlined), and is done by converting letters to numbers (A = 10, B = 11, C = 12, etc., ending up with Z = 35), then dropping the century sign, then multiplying the odd digits by 2, and even digits by 4. Then, all the numbers added up, then divided by 33. For remainders below 10, the remainder itself is the check character, otherwise pick the letter from the string "XYZABCDEFHIJKLMNOPRSTUV", where X is 10, Y is 11, Z is 12, A is 13, and so on, until it ends up with V, which is 32. Zero is often slashed (to distinguish from letter O).

Two examples of a valid Warwick Identification Number are $$ {STF \over 120491+FMB3}010 \overline{9} $$ (which is assigned to Princess Sofia the First), and $$ {ICF \over 120491+FC4R}016 \overline{1} $$ (which is assigned to Princess Isabel Castillo Flores).
