The CAS Registry Mumber 191099-41-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,1,0,9 and 9 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 191099-41:
(8*1)+(7*9)+(6*1)+(5*0)+(4*9)+(3*9)+(2*4)+(1*1)=149
149 % 10 = 9
So 191099-41-9 is a valid CAS Registry Number.

Allylation and benzylation of enoltes derived from β-phenylselanyl silyl enol ethers

Ponthieux, Sylvain,Outurquin, Francis,Paulmier, Claude

, p. 6365 - 6376 (1997)

α-Phenylselanyl γ-unsaturated ketones were obtained through allylation of enolates generated by potassium t-butoxide cleavage of β-phenylselanyl silyl enol ethers derived from α-phenylselanyl ketones. With enoxysilanes prepared from α-phenylselanyl aldehydes, O-allylation and O-benzylation of the corresponding enolates were also observed.
