Check Digit Verification of cas no

The CAS Registry Mumber 207989-27-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,7,9,8 and 9 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 207989-27:
(8*2)+(7*0)+(6*7)+(5*9)+(4*8)+(3*9)+(2*2)+(1*7)=173
173 % 10 = 3
So 207989-27-3 is a valid CAS Registry Number.

Methyltrypsin-catalyzed peptide coupling: Comparison of alkyl ester and guanidinophenyl ester derivatives as acyl donor component

Itoh, Kunihiko,Sekizaki, Haruo,Toyota, Eiko,Tanizawa, Kazutaka

, p. 307 - 319 (2007/10/03)

Methyltrypsin-catalyzed peptide synthesis has been studied by using conventional alkyl ester and p-guanidinophenyl ester derivatives of α-amino acid as the acyl donor component. They were found to be coupled with α- amino acid derivatives (acyl acceptor component) to produce dipeptide. The behavior of methyltrypsin toward both the substrates has been studied.
