Calculate Digit Verification of CAS Registry Number 403665-98:
(8*4)+(7*0)+(6*3)+(5*6)+(4*6)+(3*5)+(2*9)+(1*8)=145
145 % 10 = 5
So 403665-98-5 is a valid CAS Registry Number.

GaCl3-promoted ethenylation of thioester silyl enolate and dienolate with silylethyne

Arisawa, Mieko,Miyagawa, Chie,Yoshimura, Satoru,Kido, Yoshiyuki,Yamaguchi, Masahiko

, p. 1080 - 1081 (2007/10/03)

In the presence of GaCl3, silyl enol ethers derived from either S-alkyl or S-aryl thioesters are ethenylated at the α-carbon atom with trimethylsilylethyne in high yields. The reactions of dienolates give α,α-diethenyl thioesters.
