Check Digit Verification of cas no

The CAS Registry Mumber 1207180-89-9 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 0 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1207180-89:
(9*1)+(8*2)+(7*0)+(6*7)+(5*1)+(4*8)+(3*0)+(2*8)+(1*9)=129
129 % 10 = 9
So 1207180-89-9 is a valid CAS Registry Number.

Synthesis of 3,3-and 4,4-alkyl-phenyl-substituted pyrrolidin-2-one derivatives

Kulig,Ignasik,Malawska

experimental part, p. 1629 - 1636 (2010/07/06)

Syntheses of 3,3-and 4,4-alkyl-phenyl-substituted pyrrolidin-2-one derivatives are described. The final compounds were obtained by the reductive cyclization of relevant cyanoalkanoate esters using NaBH4 and CoCl2.6H2O. The obtained pyrroIidin-2-one derivatives are pharmacophoric fragments for the synthesis of various biologically active compounds.
