Check Digit Verification of cas no
The CAS Registry Mumber 593-96-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,9 and 3 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 593-96:
(5*5)+(4*9)+(3*3)+(2*9)+(1*6)=94
94 % 10 = 4
So 593-96-4 is a valid CAS Registry Number.

Photobromination of C2H5Cl in the Presence of C2H6. The Heat of Formation of the CH3CHCl Radical and the D0 (CH3CHCl-H) Bond Dissociation Energy
Tschuikow-Roux, E.,Salomon, D. R.

The gas-phase photobromination of C2H5Cl in the presence of ethane as competitor has been studied between 32 and 95 deg C at total reactant pressures of ca. 32 Torr and sevenfold hydrocarbon excess over bromine.Under these conditions hydrogen abstraction by bromine atoms from C2H5Cl occurs almost exclusively from the CH2Cl group.Over the temperature range stated, the relative rate constants conform to an Arrhenius rate law, which combined with the known rate parameters for ethane, log (A/cm3 mol-1 s-1) = 14.135 +/- 0.056, E = 13.66 +/- 0.14 kcal mol-1, yield for the abstraction of secondary hydrogen in CH3CH2Cl k1/cm3 mol-1 s-1 = 1E12.182+/-0.091 exp-1)/RT>.From an analysis of kinetic and thermochemical data on these and related compounds in the literature the following radical heats of formation and C-H bond dissociation energies are deduced: ΔHf0(CH3CHCl) = 16.75 +/- 1.0; D0(CH3CHCl) = 1.0; ΔHf0(CH3CHF) = -17.7 +/- 1.1; and D0(CH3CHF-H) = 97.3 +/- 1.1 kcal mol-1.
