Check Digit Verification of cas no
The CAS Registry Mumber 335-36-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,3 and 5 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 335-36:
(5*3)+(4*3)+(3*5)+(2*3)+(1*6)=54
54 % 10 = 4
So 335-36-4 is a valid CAS Registry Number.

ELECTROCHEMICAL FLUORINATION OF 4-(PERFLUORO-n-BUTYL)-n-BUTANOYL CHLORIDE

Electrochemical fluorination of 4-(perfluoro-n-butyl)-n-butanoyl chloride produces perfluorooctanoyl fluoride in higher yields than those obtained from n-octanoyl chloride, which is the usual starting material.In particular, one of the by-products of the industrial process, the cyclic perfluoroether perfluoro-2-propyl-tetrahydropyran, is not formed.Also the other by-products, except fluorocarbon perfluoro-n-heptane, are produced in lower amounts.These results are discussed and a mechanism is suggested.
ELECTROCHEMICAL FLUORINATION USING POROUS NICKEL AND FOAM NICKEL ANODES
Drakesmith, F. G.,Hughes, D. A.
, p. 103 - 134 (2007/10/02)
This work set out to examine the reasons behind some of the problems associated with ECF, namely, lack of reproducibility, low chemical yields, poor selectivity and low current densities, with a view to ameliorating these shortcomings and making the process more attractive to the chemical industry.The approach was to study the chemistry under controlled conditions of potential, reactant concentration, temperature, etc., and to analyse the results in terms of product structure, distribution and yield.Two distinct stages in the process were identified, i) the conditioning of the electrode, and, ii) the fluorination of the organic substrate.These stages are described in detail in relation to two model systems investigated, the fluorination of propene using porous and foam nickel anodes, and the fluorination of the octanoyl chloride using nickel foam anodes.The scales of experiments ranged from 100 ml to 100 l cell capacities.General conclusions are derived and recommendations made for the more efficient operation of the process.
