Identifier format invalid (European value added tax identifier (Ireland))	The European value added tax identifier in Ireland has different valid formats due to its latest adaptation in 2013. The rule checks the presence of: A) 7 numerical digits followed by 2 letters whereby the last character necessarily equals "A" or "H", B) 7 numerical digits followed by 1 character, C) 6 digits and two characters whereby the characters are either placed at the last two positions or on position two and the last one.

C8 - checksum letter, C9 is optional and can be a letter in the range [A-I], or “W”. 1. In reverse order, each digit is multiplied by a weight started at 2: C7 - 2 C6 - 3 C5 - 4 C4 - 5 C3 - 6 C2 - 7 C1 - 8 LetterToNumber(C9)- 9 2. LetterToNumber(C9) is based on the following mapping: “A”=1, “B”=2, “C”=3, “D”=4, “E”=5, “F”=6, “G”=7, “H”=8, “I”=9 A “W” or absence of character in position 9 is allocated a numeric value of 0. 3. Sum up the result (sumproduct) 4. The remainder of the modulo 23 indicates the character position on the alphabet according to the following mapping:	RELEASED	ERROR
