144760-46-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 144760-46-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,7,6 and 0 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 144760-46:
(8*1)+(7*4)+(6*4)+(5*7)+(4*6)+(3*0)+(2*4)+(1*6)=133
133 % 10 = 3
So 144760-46-3 is a valid CAS Registry Number.

Chiral organosilicon compounds in synthesis. Preparation and stereoselective alkylations of silylcinnamyl carbanions

Lamothe, S.,Cook, K. L.,Chan, T. H.

, p. 1733 - 1742 (2007/10/02)

Silylallyl carbanions of type 13 bearing a chiral lithium complexing substituent remote from silicon can be alkylated regio- and stereoselectively at the α-position by small electrophiles in nonpolar solvents.The regiochemical outcome of the reaction was found to be highly dependent on the size of the incoming electrophile.Secondary alkyl halides react preferentially at the γ-center and good levels of stereoselectivity are still obtained in nonpolar solvents despite the rather long distance between the reacting center and the chiral auxiliary.Transformation of the alkylated allylsilanes into optically active alcohols and carboxylic acids may represent a potential synthetic application of the method.
