200808-25-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 200808-25-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,0,8,0 and 8 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 200808-25:
(8*2)+(7*0)+(6*0)+(5*8)+(4*0)+(3*8)+(2*2)+(1*5)=89
89 % 10 = 9
So 200808-25-9 is a valid CAS Registry Number.

Stereoselectivity control in reactions of tertiary 2-oxacycloalkyl radicals

Gerster,Renaud

, p. 1261 - 1267 (2007/10/03)

The stereochemical outcome of reactions mediated by tertiary 1,3-dioxolan-4-yl and oxiranyl cyclic radicals has been investigated. The presence of a very bulky substituent next to the radical center has a remarkable syn directing effect. These stereoselectivities are rationalized by a model which takes into account radical pyramidalization, steric interactions between the substituents attached to the cycle and steric interactions with the incoming radical trap.
