944148-97-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 944148-97-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,4,1,4 and 8 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 944148-97:
(8*9)+(7*4)+(6*4)+(5*1)+(4*4)+(3*8)+(2*9)+(1*7)=194
194 % 10 = 4
So 944148-97-4 is a valid CAS Registry Number.

A general route to 4-C-substituted pyrimidine nucleosides
Hennecke, Ulrich,Kuch, David,Carell, Thomas
, p. 929 - 935 (2007)
Palladium-catalyzed cross-coupling reactions of tin and zinc nucleophiles with arylsulfonates of pyrimidine nucleosides have been achieved to give a wide range of 4-C-substituted pyrimidine nucleosides. This method also allows the construction of pyrimidi
