Check Digit Verification of cas no

The CAS Registry Mumber 118722-81-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,7,2 and 2 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 118722-81:
(8*1)+(7*1)+(6*8)+(5*7)+(4*2)+(3*2)+(2*8)+(1*1)=129
129 % 10 = 9
So 118722-81-9 is a valid CAS Registry Number.

Effect of Substituent on Reactions Remote from Silicon: Regioselective α-Alkylation of α-Silylallyl Carbanions

Horvath, Raymond F.,Chan, Tak Hang

, p. 317 - 327 (2007/10/02)

α-Silylallyl carbanions having metal-ion complexing substituents on silicon react with alkyl halides to give α-substituted allylsilanes regioselectively.The extent of α-selection depends significantly on the nature of the ligand and solvent.The synthetic utility of these systems is demonstrated by application in the synthesis of α-(E)-bisabolene.
