Check Digit Verification of cas no

The CAS Registry Mumber 1332525-41-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,2,5,2 and 5 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1332525-41:
(9*1)+(8*3)+(7*3)+(6*2)+(5*5)+(4*2)+(3*5)+(2*4)+(1*1)=123
123 % 10 = 3
So 1332525-41-3 is a valid CAS Registry Number.

Coupling reaction between electron-rich pyrimidinones and α-amino acids promoted by phosphonium salts

Elmarrouni, Abdelatif,Fabrellas, Josep M.,Heras, Montserrat

experimental part, p. 5967 - 5977 (2011/10/09)

Coupling reaction between electron-rich 2-morpholino-4(3H)-pyrimidinone and nucleophilic side chains of several natural α-amino acids promoted by phosphonium salt has been developed to prepare new optically active pyrimidin-4-yl amino acids. The best results were obtained using a two-step method through the easily available benzotriazolyl-1-oxy intermediate. A detailed optimization study of this reaction is discussed.
