16183-00-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 16183-00-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,1,8 and 3 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 16183-00:
(7*1)+(6*6)+(5*1)+(4*8)+(3*3)+(2*0)+(1*0)=89
89 % 10 = 9
So 16183-00-9 is a valid CAS Registry Number.

Homogeneous Rate Constants for Coupling between Electrochemically Generated Aromatic Anion Radicals and Alkyl Radicals

Pedersen, Steen U.,Lund, Torben

, p. 397 - 402 (2007/10/02)

Rate constants have been measured for the coupling between hexenyl radicals and 2,2-dimethylhexenyl radicals and electrogenerated anion radicals of anthracene, 9,10-diphenylanthracene, benzophenone and quinoxaline.The rate constant for all four reactions in N,N-dimethylformamide is log k2 = 9.1(5), which is in accordance previous results in 1,2-dimethoxyethane for naphthalene and benzophenone anion radicals and 1-hexenyl radicals.The data indicate that the redox potential of the aromatic anion radical has only a minor influence on the rate of coupling with alkyl radicals.The rate constants for anion radicals of 9,10-diphenylanthracene and benzophenone were somewhat lower, 6(1) x 108 M-1 s-1, which for 9,10-diphenylanthracene might be caused by steric hindrance by the two phenyl groups.The conclusion is that the coupling reaction between aromatic anion radicals and alkyl radicals has all the characteristics of a radical-radical coupling.
