Check Digit Verification of cas no
The CAS Registry Mumber 161531-53-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,5,3 and 1 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 161531-53:
(8*1)+(7*6)+(6*1)+(5*5)+(4*3)+(3*1)+(2*5)+(1*3)=109
109 % 10 = 9
So 161531-53-9 is a valid CAS Registry Number.

Direct fluorination of 1,3-dicarbonyl compounds
Chambers, Richard D.,Greenhall, Martin P.,Hutchinson, John
, p. 1 - 8 (2007/10/02)
In acid media, 1,3-diketones and 1,3-keloesters can be fluorinated in high yield and often with high conversion mainly to the corresponding 2-fluoro- compounds. Diesters such as diethyl malonate do not react with fluorine under the same reaction conditions. The mechanism of these reactions has been investigated and while the identity of the electrophilic fluorinating species is uncertain, we believe that the essential features of the reaction pathway are understood.
