834966-32-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 834966-32-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,3,4,9,6 and 6 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 834966-32:
(8*8)+(7*3)+(6*4)+(5*9)+(4*6)+(3*6)+(2*3)+(1*2)=204
204 % 10 = 4
So 834966-32-4 is a valid CAS Registry Number.

Synthesis of organosilicon polymers by using the Lewis-acid-catalyzed trans-allylsilylation of alkynes

Asao, Naoki,Tomeba, Hisamitsu,Yamamoto, Yoshinori

, p. 27 - 30 (2007/10/03)

The HfCl4 catalyzed polymerization of allyl(4-ethynylphenyl) dimethylsilane (1a) proceeded smoothly to give poly[dimethyl-(1,4-pentadienyl) phenylsilane] (2a), and the HfCl4 catalyzed reaction of 1-allyl-2-(4-ethynyphenyl)-1,1,2,2-tetramethyldisilane (1b) afforded poly[1,1,2,2-tetramethyl-1-(1,4-pentadienyl)-2-phenyldisilane] (2b). These polymerization reactions proceeded via the stereoselective trans-allylsilylation of the 4-ethynyl group attached to the aromatic ring.
