Check Digit Verification of cas no

The CAS Registry Mumber 1207187-93-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,7,1,8 and 7 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1207187-93:
(9*1)+(8*2)+(7*0)+(6*7)+(5*1)+(4*8)+(3*7)+(2*9)+(1*3)=146
146 % 10 = 6
So 1207187-93-6 is a valid CAS Registry Number.

A simple approach for the synthesis of new pyrimidinyl α-amino acids

Elmarrouni, Abdelatif,Güell, Mireia,Collell, Cristina,Heras, Montserrat

experimental part, p. 612 - 623 (2010/09/14)

A simple synthetic method for the preparation of optically active pyrimidinyl α-amino acids is presented. A nucleophilic ipso-substitution reaction between 2-(benzylsulfonyl)-4-isopropoxypyrimidines and a nucleophilic side chain of several protected natural α-amino acids is investigated to obtain new pyrimidin-2-yl α-amino acids. A detailed optimisation study of this reaction is discussed. Moreover, the selective O-alkylation of 2-(benzylsulfanyl)-4(3H)pyrimidinones with a hydroxylic side chain of some natural α-amino acids under Mitsunobu conditions is studied as a method to prepare new pyrimidin-4-yl α-aminoesters.
