Check Digit Verification of cas no

The CAS Registry Mumber 219866-68-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,8,6 and 6 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 219866-68:
(8*2)+(7*1)+(6*9)+(5*8)+(4*6)+(3*6)+(2*6)+(1*8)=179
179 % 10 = 9
So 219866-68-9 is a valid CAS Registry Number.

Catalyzed fluorination of carbonyl compounds

-

, (2008/06/13)

The present invention provides a method of substituting a carbonyl compound with fluorine at the α-position, comprising reaching the carbonyl compound with a fluorinating present of a metal-containing catalyst. The reaction results in replacement of a hydrogen atom by fluorine. The catalyst, which is used in a catalytically effective amount, is preferably a transition metal. In one class of methods the catalyst is a transition metal compound. In another class of methods, the catalyst is an elemental metal, in which case the carbonyl compound has an activating group attached to the carbon atom which is substituted by fluorine.

Elemental fluorine. Part 9 : Catalysis of the direct fluorination of 2-substituted carbonyl compounds

Chambers, Richard D.,Hutchinson, John

, p. 45 - 52 (2007/10/03)

Catalysis of the reaction between fluorine and a range of 2-substituted carbonyl compounds has been investigated. Most notably, the preparation of diethyl-2-fluoromalonate has been achieved in high yield by fluorination of diethylmalonate in the presence of hydrated copper nitrate. Reactions between fluorine and carbanions derived from 2-substituted carbonyl compounds, including phosphonates, sulphones and nitriles, are also discussed.
