Check Digit Verification of cas no

The CAS Registry Mumber 268737-86-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,8,7,3 and 7 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 268737-86:
(8*2)+(7*6)+(6*8)+(5*7)+(4*3)+(3*7)+(2*8)+(1*6)=196
196 % 10 = 6
So 268737-86-6 is a valid CAS Registry Number.

Solid-phase synthesis of carbocyclic nucleosides.

Crimmins,Zuercher

, p. 1065 - 1067 (2007/10/03)

[formula: see text] An efficient solid-phase synthesis of carbocyclic nucleosides has been developed. The key step is the palladium-catalyzed coupling of a purine derivative to a resin-bound allylic benzoate. The resulting products may be further functionalized on the solid phase. Acidic cleavage affords carbocyclic nucleosides, a class of compounds with demonstrated biological activity and substantial current interest.
