215927-11-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 215927-11-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,5,9,2 and 7 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 215927-11:
(8*2)+(7*1)+(6*5)+(5*9)+(4*2)+(3*7)+(2*1)+(1*1)=130
130 % 10 = 0
So 215927-11-0 is a valid CAS Registry Number.

Synthesis of prodrugs as bridged nucleosides
Hatlelid, Jostein,Benneche, Tore,Undheim, Kjell
, p. 1270 - 1274 (2007/10/03)
Methods for the preparation of N, N'-connected bisnucleosides have been developed. The bridge is formally a carbonate ester of N-hydroxymethyl nucleosides. Both symmetrical and non-symmetrical bridged bisnucleosides are available. Acta Chemica Scandinavica 1998.
