Check Digit Verification of cas no

The CAS Registry Mumber 740801-52-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,4,0,8,0 and 1 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 740801-52:
(8*7)+(7*4)+(6*0)+(5*8)+(4*0)+(3*1)+(2*5)+(1*2)=139
139 % 10 = 9
So 740801-52-9 is a valid CAS Registry Number.

Synthesis of aza-analogues of Ganciclovir

Koszytkowska-Stawińska, Mariola,Sas, Wojciech,De Clercq, Erik

, p. 10325 - 10331 (2007/10/03)

Aza-analogues of ganciclovir have been prepared via coupling of nucleobases with N-[2-pivaloyloxy-1-(pivaloyloxymethyl)ethyl]methanesulfonamide or 3-mesyl-4-(benzoyloxymethyl)-1,3-oxazolidine.

Facile synthesis of acyclic azanucleosides from N-pivaloyloxymethyl amides and sulfonamides: Synthesis of aza-analogues of Ganciclovir

Koszytkowska-Stawińska, Mariola,Sas, Wojciech

, p. 5437 - 5440 (2007/10/03)

N-Pivaloyloxymethyl amides and sulfonamides, readily available from N-alkylation of both amides and sulfonamides with commercial chloromethyl pivaloate, were converted into acyclic azanucleosides via a one-pot base silylation/nucleoside coupling procedure
