146904-29-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 146904-29-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,9,0 and 4 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 146904-29:
(8*1)+(7*4)+(6*6)+(5*9)+(4*0)+(3*4)+(2*2)+(1*9)=142
142 % 10 = 2
So 146904-29-2 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
