Check Digit Verification of cas no

The CAS Registry Mumber 135103-64-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,1,0 and 3 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 135103-64:
(8*1)+(7*3)+(6*5)+(5*1)+(4*0)+(3*3)+(2*6)+(1*4)=89
89 % 10 = 9
So 135103-64-9 is a valid CAS Registry Number.

A novel nucleophilic substitution of in situ generated 3-tert-butyldimethyl-silyloxyalk-2-enylsulfonium salts with allylindium reagents

Lee, Phil Ho,Lee, Kooyeon,Kim, Sunggak

, p. 3205 - 3207 (2001)

(equation presented) In situ generated 3-tert-butyldimethylsilyloxyalk-2-enylsulfonium salts derived from the reaction of α,β-enones with dimethyl sulfide in the presence of TBSOTf undergo a novel nucleophilic substitution with in situ generated allylindium reagents from indium and allyl halides to give silyl enol ethers of δ,ε-unsaturated ketones, which correspond to Michael addition products, in good yields. ?

Trialkylsilyl triflate promoted conjugate addition of allylstannes to α,β-enones

Kim,Lee

, p. 25 - 29 (2007/10/02)

Trialkylsilyl triflates promote conjugate additon of allylstannes to α,β-enones to afford β-alkylated silyl enol ethers in high yields.
