72653-51-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 72653-51-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,6,5 and 3 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 72653-51:
(7*7)+(6*2)+(5*6)+(4*5)+(3*3)+(2*5)+(1*1)=131
131 % 10 = 1
So 72653-51-1 is a valid CAS Registry Number.

The synthesis of α-acetoxy sulfides and their Lewis acid-mediated reactions

Kraus, George A.

, p. 2599 - 2602 (2007/10/02)

α-Acetoxy sulfides can be conveniently prepared by the reaction of dithioacetals with mercuric acetate at ambient temperature. They react with allyltrimethylsilane, enol silyl ethers, and cyanotrimethylsilane in the presence of SnCl4 to afford

α-Alkylation and α-alkylidenation of carbonyl compounds: Lewis acid-promoted phenylthioalkylation of o-silylated enolates

Paterson, Ian,Fleming, Ian

, p. 2179 - 2182 (2007/10/11)

The O-silylated enolates of ketones, aldehydes, esters, and lactones can be phenylthioalkylated in the presence of Lewis acids; reductive or oxidative sulphur-removal gives the regiospecifically α-alkylated or alkylidenated carbonyl compounds.
