731853-22-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 731853-22-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,3,1,8,5 and 3 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 731853-22:
(8*7)+(7*3)+(6*1)+(5*8)+(4*5)+(3*3)+(2*2)+(1*2)=158
158 % 10 = 8
So 731853-22-8 is a valid CAS Registry Number.

Silver-catalyzed [2 + 2] cycloadditions of siloxy alkynes

Sweis, Randy F.,Schramm, Michael P.,Kozmin, Sergey A.

, p. 7442 - 7443 (2004)

We have described the first [2 + 2] cycloadditions of siloxy alkynes with a range of unsaturated carbonyl compounds. The reactions are efficiently promoted by substoichiometric amount of silver trifluoromethanesulfonimide and display excellent regio- and diastereoselectivity combined with a broad substrate scope. Our studies have established unambiguously the stepwise mechanism of this process and provided evidence for a novel role of silver in the catalytic cycle of the reaction, which involves silver-based complexation and activation of siloxy alkyne toward the subsequent 1,4-addition.
