496854-17-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 496854-17-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,6,8,5 and 4 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 496854-17:
(8*4)+(7*9)+(6*6)+(5*8)+(4*5)+(3*4)+(2*1)+(1*7)=212
212 % 10 = 2
So 496854-17-2 is a valid CAS Registry Number.

Novel 10- and 20-membered tin- and silicon-containing rings: Synthesis, complexation behavior, and conversion into a lewis acidic polymer

Schulte, Marcus,Gabriele, Giuseppina,Schuermann, Markus,Jurkschat, Klaus,Duthie, Andrew,Dakternieks, Dainis

, p. 328 - 336 (2008/10/08)

Reaction of the dimethylsilylmethyl-substituted tetraorganotin derivative CH2[CH2Sn(Ph2)CH2Si(H)Me2 ]2 (1) and CH2[CH2Sn(Ph2)CH2Si(i-PrO)Me2 ]2 (3), respectively, with mercuric chloride afforded the novel silicon- and tin-containing 10- and 20-membered rings cyclo-CH2[CH2Sn(Cl2)CH2Si(Me2 )]2O (4) and cyclo-CH2[CH2Sn(Cl2)CH2Si(Me2 )OSi(Me2)CH2Sn(Cl2)CH2]2 CH2 (5). Both compounds 4 and 5 can be converted into the soluble Lewis acidic polymer poly-[Si(Me2)CH2Sn(Cl2)(CH2)3 Sn(Cl2)CH2Si(Me2)O] (8). 119Sn NMR studies indicate that 4 acts as a bidentate Lewis acid toward chloride ions, exclusively forming the 1:1 complex [cyclo-CH2[CH2Sn(Cl2)CH2Si(Me2 )]2O·Cl]-[(Ph3P)2N]+ (7). The molecular structures as determined by single-crystal X-ray diffraction analysis of 4 and 7 are reported.
