773133-81-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 773133-81-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,7,3,1,3 and 3 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 773133-81:
(8*7)+(7*7)+(6*3)+(5*1)+(4*3)+(3*3)+(2*8)+(1*1)=166
166 % 10 = 6
So 773133-81-6 is a valid CAS Registry Number.

Synthesis of 2-substituted 6-(hydroxymethyl)purine bases and nucleosides
Silhar, Peter,Pohl, Radek,Votruba, Ivan,Hocek, Michal
, p. 1669 - 1695 (2007/10/03)
A facile and efficient methodology of the synthesis of 6-(hydroxymethyl) purine derivatives (bases and nucleosides) was developed based on Pd-catalyzed cross-coupling reactions of 6-halopurines or N-protected 2-amino-6-halopurines with (benzoyloxymethyl)z
