Check Digit Verification of cas no

The CAS Registry Mumber 83004-40-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,0,0 and 4 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 83004-40:
(7*8)+(6*3)+(5*0)+(4*0)+(3*4)+(2*4)+(1*0)=94
94 % 10 = 4
So 83004-40-4 is a valid CAS Registry Number.

The reinvestigation of the kinetics of the reactions of fluorodi(4-nitrophenyl)ethanes with sodium methoxide in methanol

Leffek, Kenneth T.,Schroeder, Grzegorz

, p. 1696 - 1701 (1982)

The procedure previously described for the preparation of 1-fluoro-2,2-di(4-nitrophenyl)ethane actually yields 1,1,2-tri(4-nitrophenyl)ethane.Fluoro-2,2-di(4-nitrophenyl)ethane has been prepared and rate constants, isotope effects, and activation parameters for the β-elimination reaction with methoxide ion in methanol are reported.These parameters indicate a concerted E2 mechanism, with a fairly symmetrical transition state.The subsequent dimerization reaction of the olefin product to yield 1,1,3,3-tetra(4-nitrophenyl)butene-1 is described.The reaction of 1,1,1-trifluoro-2,2-di(4-nitrophenyl)ethane with methoxide ion in methanol has been reinvestigated and the reaction on the first product 1,1-difluoro-2,2-di(4-nitrophenyl)ethylene with excess methoxide, to give di(4-nitrophenyl)ketene dimethylacetal in a multistep reaction, is reported.

The kinetics, isotope effects, and mechanism of the reaction of 2,2-di(4-nitrophenyl)-1,1,1-trifluoroethane with alkoxide bases in alcohol solvents

Jarczewski, Arnold,Schroeder, Grzegorz,Galezowski, Wlodzimierz,Leffek, Kenneth T.,Maciejewska, Urszula

, p. 576 - 580 (2007/10/02)

The reaction between 2,2-di(4-nitrophenyl)-1,1,1-trifluoroethane and the alkoxide bases O-CH3, O-C2H5, O-nC4H9, O-CH(CH3)2 and O-C(CH3)3 in their corresponding alcohol solvents is a multistep reaction
