In this work the undetected error probability performance of the proposed in the technical specification of 5G new radio cyclic redundancy-check codes taking into consideration that they have to work for fixed interval of lengths are investigated. Codes of 6, 11 and 16 check bits with better error detection performance than the proposed in the specification ones are suggested. For 24 check bits the 3 best CRC codes are presented, but no only one best for the whole interval of lengths code was found.
