79240-19-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 79240-19-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,2,4 and 0 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 79240-19:
(7*7)+(6*9)+(5*2)+(4*4)+(3*0)+(2*1)+(1*9)=140
140 % 10 = 0
So 79240-19-0 is a valid CAS Registry Number.

Further Radical Induced Cyclisations of Unsaturated Sulfones
Harvey, Iain W.,Whitham, Gordon H.
, p. 185 - 190 (2007/10/02)
Radical induced cyclisations of unsaturated sulfones by the endo-5-exo- and the exo-5-exo-ipso-modes are described.Thus the unsaturated allylic sulfones 4, 6 and 8 underwent cyclisation to the cyclopentyl sulfones 5, 7, and 9 and 10 respectively, while th
