RegEx for ISIN with at least 1 number
I have the following RegEx to parse ISIN of fonds, assets, etc.. (2 characters followed by 10 digits and characters)
([A-Z]{2})([A-Z0-9]{10})
But this also marks for example a word like this ABCDEFGHIJKL, but this is no real ISIN. A definition of ISINs is here: WIKI
So some examples are US45256BAD38, US64118Q1076, XS0884410019. What would be the correct RegEx to search for them, without matches like ABCDEFGHIJKL?
Maybe with a RegEx to have at least one number?

You can use a lookahead regex:
b([A-Z]{2})((?![A-Z]{10}b)[A-Z0-9]{10})b
RegEx Demo
(?![A-Z]{10}b) is a negative lookahead that will fail the match if all 10 chars are letters after first 2 chars.

Thanks! This works fine in the demo, but I use it in PLSQL with REGEXP_SUBSTR and there it fails.. do you know if REGEXP_SUBSTR does not support lookaheads?

Hmm you didn't mention this in question. I'm not sure if Oracle regex supports lookahead. Check documentation.

Yes I thought that this would be no problem for Oracle, but in fact Oracle doesn't support lookahead and lookbehind. You answered my question so thanks! I just asked the wrong question

If you can not use lookahead according to the Wikipedia defintion you can also just check if the last character is a number as it should be the check digit.
ISINs consist of two alphabetic characters, which are the ISO 3166-1 alpha-2 code for the issuing country, nine alpha-numeric characters (the National Securities Identifying Number, or NSIN, which identifies the security, padded as necessary with leading zeros), and one numerical check digit.

([A-Z]{2})([A-Z0-9]{9})([0-9]{1})
