Calculate Digit Verification of CAS Registry Number 857062-26:
(8*8)+(7*5)+(6*7)+(5*0)+(4*6)+(3*2)+(2*2)+(1*6)=181
181 % 10 = 1
So 857062-26-1 is a valid CAS Registry Number.

A highly efficient synthesis of rocaglaols by a novel α-arylation of ketones

Diedrichs, Nicole,Ragot, Jacques P.,Thede, Kai

, p. 1731 - 1735 (2007/10/03)

Rocaglaols are natural products exhibiting a range of biological activities. A new synthetic method for the α-arylation of ketones allows for the synthesis of previously inaccessible rocaglaol derivatives. The key sequence consists of a previously unreported Suzuki type reaction using brominated si-lyl enol ethers as substrates followed by deprotection of the arylated silyl enol ethers.
