convert_isbn ~113 tokens
Convert an ISBN between ISBN-10 and ISBN-13 (recomputing the check digit). ISBN-10 -> ISBN-13 prefixes "978"; ISBN-13 -> ISBN-10 works only for the 978 prefix.
validate_isbn ~134 tokens
Validate an ISBN-10 or ISBN-13 (keyless, offline): detects the format and checks the check digit (ISBN-10 uses mod-11 with an "X" for 10). Hyphens/spaces ignored. Validates the number, not the book.
