296787-91-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 296787-91-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,6,7,8 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 296787-91:
(8*2)+(7*9)+(6*6)+(5*7)+(4*8)+(3*7)+(2*9)+(1*1)=222
222 % 10 = 2
So 296787-91-2 is a valid CAS Registry Number.

Beckmann, Jens,Jurkschat, Klaus,Rabe, Stephanie,Schürmann, Markus,Dakternieks, Dainis,Duthie, Andrew
, p. 3272 - 3279 (2000)
Small amounts of [Ph2(OH)Sn]2CH2 effectively catalyze the condensation of Ph2Si(OH)2 to give cyclo-(Ph2SiO)4 in good yield. The reaction proceeds under remarkably mild conditions
