Check Digit Verification of cas no
The CAS Registry Mumber 114021-28-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,4,0,2 and 1 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 114021-28:
(8*1)+(7*1)+(6*4)+(5*0)+(4*2)+(3*1)+(2*2)+(1*8)=62
62 % 10 = 2
So 114021-28-2 is a valid CAS Registry Number.

SYNTHESIS OF 4-C SUBSTITUTED PYRIMIDINE NUCLEOSIDES
Bischofberger, Norbert
, p. 2821 - 2824 (2007/10/02)
t-Butyldimethylsilyl protected uridine and thyimidine were converted to the 4-O-triisopropylsulfonyl derivatives 3 and 4, respectively. 3 and 4 underwent clean displacements with mmalonate-type nucleophiles yielding the 4-C-substituted pyrimidine nucleosi
