Check Digit Verification of cas no

The CAS Registry Mumber 1421929-71-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,1,9,2 and 9 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1421929-71:
(9*1)+(8*4)+(7*2)+(6*1)+(5*9)+(4*2)+(3*9)+(2*7)+(1*1)=156
156 % 10 = 6
So 1421929-71-6 is a valid CAS Registry Number.

Efficient synthesis of gemcitabine 5′-O-triphosphate using gemcitabine 5′-O-phosphoramidate as an intermediate

Kaczmarek, Renata,Radzikowska, Ewa,Baraniak, Janina

, p. 1851 - 1854 (2014)

A new efficient approach for the synthesis of gemcitabine triphosphate has been developed. The method is based on the ring-opening reaction of 2-cyanoethoxy-2-oxo-1,3,2-oxathiaphospholane with protected gemcitabine in the presence of DBU. Subsequent treatment of gemcitabine monophosphate with DCC in the presence of ammonia provides gemcitabine 5′-O-phosphoramidate. Finally, this compound, on reaction with pyrophosphate, furnishes gemcitabine 5′-triphosphate in 50% yield. Georg Thieme Verlag Stuttgart. New York.
