Check Digit Verification of cas no
The CAS Registry Mumber 120801-50-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,8,0 and 1 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 120801-50:
(8*1)+(7*2)+(6*0)+(5*8)+(4*0)+(3*1)+(2*5)+(1*0)=75
75 % 10 = 5
So 120801-50-5 is a valid CAS Registry Number.

Radical Induced Cyclisations of Some Cyclic Unsaturated Allylic Sulphones
Smith, Thomas A.K.,Whitham, Gordon H.
, p. 313 - 317 (2007/10/02)
The cyclisations of unsaturated allylic p-tolyl sulphones to give ring compounds with adjacent vinyl and p-tolylsulphonylmethyl substituents (Scheme 2) is shown to be a feasible process by the conversion, in satisfactory yield, of the allylic ether (5; R=
