Check Digit Verification of cas no

The CAS Registry Mumber 107960-03-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,9,6 and 0 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 107960-03:
(8*1)+(7*0)+(6*7)+(5*9)+(4*6)+(3*0)+(2*0)+(1*3)=122
122 % 10 = 2
So 107960-03-2 is a valid CAS Registry Number.

Novel Preparation of N-Protected Amino Acid Active Esters Using 1,2,2,2-Tetrachloroethyl Carbonates

Jaoudai, Mahmoud,Martinez, Jean,Castro, Bertrand

, p. 2364 - 2367 (1987)

1,2,2,2-Tetrachloroethyl chloroformate reacts with substituted phenols or N-hydroxy imides to yield crystalline and stable mixed aryl or oximido tetrachloroethyl carbonates.When allowed to react with an N-protected amino acid derivative, these compounds proved to be efficient for the syntheses of the corresponding active esters.A series of active esters including p-nitrophenol, trichlorophenol, pentafluorophenol, and N-hydroxysuccinimide derivatives were prepared by this new procedure.
