# ^\D{3,} = Match any character that is NOT a digit (3 or more repetitions) - include NOV, exclude N1V ..
# \w{2} = Match any alphanumeric character (2 chars only) - covers short name like NOV1K10
# \d{2,} = Match any digit (2 or more chars) - covers NOVAK10, NOVAK102
# (?!\w) = .. not followed by any other char (a-z) .. což je ale divný protože \D je přepínač pro NONDIGIT a to když tam dám tak regex nefakčí
