Check Digit Verification of cas no

The CAS Registry Mumber 313271-63-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,3,2,7 and 1 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 313271-63:
(8*3)+(7*1)+(6*3)+(5*2)+(4*7)+(3*1)+(2*6)+(1*3)=105
105 % 10 = 5
So 313271-63-5 is a valid CAS Registry Number.

Free-radical chemistry: Part XII: Radical reactions of trifluoroethene

Chambers, Richard D.,Gilani, Anwar H.S.,Gilbert, Alan F.,Hutchinson, John,Powell, Richard L.

, p. 53 - 67 (2007/10/03)

Free-radical chemistry of trifluoroethene (3FE) is explored. Chain-shortening by telomerisation with acetone occurs and the product is successfully fluorinated to a corresponding perfluorinated material. Other telomerisation reactions involving alcohols, ethers and amines are described and the importance of polar effects on radical reactivity is highlighted. Reactions of alcohol derived telomers with base yields oxetanes and oxiranes which are polymerised to corresponding fluorinated polyethers. Further reactions of telomers are discussed.
