426-02-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 426-02-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,2 and 6 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 426-02:
(5*4)+(4*2)+(3*6)+(2*0)+(1*2)=48
48 % 10 = 8
So 426-02-8 is a valid CAS Registry Number.

Kinetics and mechanism of the thermal gas-phase reaction between NO2 and trifluorochloroethene

Romano, Rosana M.,Della Vedova, Carlos O.,Czarnowski, Joanna

, p. 1203 - 1217 (2007/10/03)

The reaction of NO2 with CF2CFCl has been studied at 322.8, 332.2 and 342.2 K, using a conventional static system. The initial pressure of CF2CFCl was varied between 13.0 and 90.2 Torr and that of NO2 between 9.3 and 89.5 Torr. Several experiments were carried out in presence of CF4, varying its pressure from 277.6 to 458.5 Torr. Three products were formed: O2NCF2CFClNO2 and equimolecular amounts n tso ClNO and O2NCF2C(O)F. The product distribution was independent of the initial pressures of the reactants and the total pressure, but the ratio of O2NCF2C(O)F to that of O2NCF2CFClNO2 increased with temperature. The reaction is homogeneous and independent of the total pressure. The following mechanism was postulated to explain the experimental results: 1. NO2 + CF2CFCl → O2NCF2CFCl? 2. O2NCF2CFCl? + NO2 + M → O2NCF2CFClNO2 + M 3. O2NCF2CFCl? + NO2 → O2NCF2C(O)F+ClNO k1 = (1.7±0.4) × 106exp(-(10.8 ±1)kcal mol-1RT) dm-3 mo1-1 s-1 k3 = (9.8±3)×1010 exp(-(1.1 ±0.2) kcal mol-1/RT) dm3 mol-1 s-1.
