91920-09-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91920-09-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,9,2 and 0 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 91920-09:
(7*9)+(6*1)+(5*9)+(4*2)+(3*0)+(2*0)+(1*9)=131
131 % 10 = 1
So 91920-09-1 is a valid CAS Registry Number.

DIE ERSTEN CF3-SUBSTITUIERTEN ORGANYL(CHLOR)SILANE
Ruppert, Ingo,Schlich, Klaus,Volbach, Wolfgang
, p. 2195 - 2198 (2007/10/02)
The three component reaction (Et2N)3P/CF3Br/R(n)SiCl(4-n) ( n= 1, 2, 3; R=CH3, Ph) gives CF3-substituted organyl (chloro)silanes for the first time.Their genesis will be elucidated.
