Check Digit Verification of cas no

The CAS Registry Mumber 191099-37-3 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, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 191099-37:
(8*1)+(7*9)+(6*1)+(5*0)+(4*9)+(3*9)+(2*3)+(1*7)=153
153 % 10 = 3
So 191099-37-3 is a valid CAS Registry Number.

Direct synthesis of regioselective α-allyl α-selanyl ketones and selanyl tetra-hydrofurans

Sahoo, Sushree Ranjan,Sarkar, Debayan,Singh, Rajat Kumar

, (2020)

An efficient approach for the synthesis of α-allyl α-selanyl ketone and selanyl tetrahydrofurans has been reported in this present work. The sodium methoxide (MeONa) mediated one pot three-component synthesis lead towards a good to an excellent yield of products with a wide substrate scope. The selenylated ketones can be important point towards important organic synthons.

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

Ponthieux, Sylvain,Outurquin, Francis,Paulmier, Claude

, p. 6365 - 6376 (2007/10/03)

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.
