Check Digit Verification of cas no

The CAS Registry Mumber 331955-29-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,1,9,5 and 5 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 331955-29:
(8*3)+(7*3)+(6*1)+(5*9)+(4*5)+(3*5)+(2*2)+(1*9)=144
144 % 10 = 4
So 331955-29-4 is a valid CAS Registry Number.

Superiority of the carbamoylmethyl ester as an acyl donor for the kinetically controlled amide-bond formation mediated by α-chymotrypsin

Miyazawa, Toshifumi,Ensatsu, Eiichi,Yabuuchi, Nobuhiro,Yanagihara, Ryoji,Yamada, Takashi

, p. 390 - 395 (2007/10/03)

The superiority of the carbamoylmethyl ester as an acyl donor for the α-chymotrypsin-catalysed kinetically controlled peptide-bond formation is demonstrated in the couplings of an inherently poor amino acid substrate, Ala, with various amino acid residues as amino components and in the couplings of non-protein amino acids such as halogenophenylalanines as carboxylic components. Furthermore, this approach is applied to the amide-bond formation between an amino acid residue and a chiral amine, which is highly diastereoselective.
