26443-88-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 26443-88-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,4,4 and 3 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 26443-88:
(7*2)+(6*6)+(5*4)+(4*4)+(3*3)+(2*8)+(1*8)=119
119 % 10 = 9
So 26443-88-9 is a valid CAS Registry Number.

Kinetics of C2F5 Radical Reactions with HCCl3 and DCCl3 in tha Gas Phase

Drys, Andrzej,Ratajczak, Emil

, p. 569 - 575 (2007/10/02)

The kinetics of pentafluoroethyl radical reactions with trichloromethane and d-trichloromethane have been studied in the static system using perfluoropropionic anhydride as a photolytic source of C2F5 radicals.The Arrhenius parameters for C2F5 radical reactions with HCCl3 and DCCl3 , based on log A 3 mol-1 s-1> = 13.40 and E=0 for the recombination reaction of C3F5 radicals, are: .The magnitude of the primary kinetic isotope effect, i.e. kH/kD=6.7 +/-4.3 at 400 K is shown to be slightly larger than might be expected on the basis of standard zero-point energy model.
