99285-70-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 99285-70-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,2,8 and 5 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 99285-70:
(7*9)+(6*9)+(5*2)+(4*8)+(3*5)+(2*7)+(1*0)=188
188 % 10 = 8
So 99285-70-8 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=

The Radical-induced Cyclisation of Some Unsaturated Allylic Sulphones

Smith, Thomas A. K.,Whitham, Gordon H.

, p. 897 - 898 (2007/10/02)

Conditions are described which promote the isomerisation of some suitably constituted unsaturated allylic sulphones to products derived apparently by a radical chain cyclisation mechanism.
