Check Digit Verification of cas no

The CAS Registry Mumber 1337538-58-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,7,5,3 and 8 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1337538-58:
(9*1)+(8*3)+(7*3)+(6*7)+(5*5)+(4*3)+(3*8)+(2*5)+(1*8)=175
175 % 10 = 5
So 1337538-58-5 is a valid CAS Registry Number.

In situ formation of N-trifluoroacetoxy succinimide (TFA-NHS): One-pot formation of succinimidyl esters, N-trifluoroacetyl amino acid succinimidyl esters, and N-maleoyl amino acid succinimidyl esters

Leonard, Nicholas M.,Brunckova, Jarmila

experimental part, p. 9169 - 9174 (2011/12/16)

A method for the in situ formation of N-trifluoroacetoxy succinimide (TFA-NHS) and its application in the formation of succinimidyl esters is presented. The developed method provides N-trifluoroacetyl and N-maleoyl amino acid succinimidyl esters from a variety of amino acids using a one-pot, high-yielding protocol. Investigations into the formation of an N-maleoyl amino acid succinimidyl ester supported the proposal of a revised reaction mechanism, and contributed to the optimization of the reaction conditions.
