Check Digit Verification of cas no

The CAS Registry Mumber 250722-00-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,0,7,2 and 2 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 250722-00:
(8*2)+(7*5)+(6*0)+(5*7)+(4*2)+(3*2)+(2*0)+(1*0)=100
100 % 10 = 0
So 250722-00-0 is a valid CAS Registry Number.

Functionalization of saturated fluorocarbons with and without light

Chen, Xudong,Lemal, David M.

, p. 1158 - 1167 (2008/09/19)

Photochemical transformation of saturated fluorocarbons into tetrabutylammonium enolates has been improved, and a method employing ketyls as reductants has been developed that accomplishes the same chemistry without light. Enolates have been isolated as enol methyl ethers, from which they can be efficiently regenerated with tetrabutylammonium iodide. In other cases, enolates have been isolated as the corresponding ketone or stable enol. Fluorocarbon LUMO energies correlate with their reactivity and serve as a guide to the choice of ketyl. Use of this chemistry for fluoropolymer surface modification is discussed.
