Check Digit Verification of cas no

The CAS Registry Mumber 307309-80-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,7,3,0 and 9 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 307309-80:
(8*3)+(7*0)+(6*7)+(5*3)+(4*0)+(3*9)+(2*8)+(1*0)=124
124 % 10 = 4
So 307309-80-4 is a valid CAS Registry Number.

Synthesis of nucleoside boranophosphoramidate prodrugs conjugated with amino acids

Li, Ping,Shaw, Barbara Ramsay

, p. 2171 - 2183 (2007/10/03)

(Chemical Equation Presented) Nucleoside boranophosphates and nucleoside amino acid phosphoramidates have been shown to be potent antiviral and anticancer agents with the potential to act as nucleoside prodrugs. A combination of these two types of compoun

Model synthesis of nucleoside boranophosphoramidate with amino acid for prodrug purpose

Li, Ping,Shaw, Barbara Ramsay

, p. 675 - 678 (2008/02/03)

A model synthesis of a nucleoside boranophosphoramidate prodrug with (L)-tryptophan methyl ester was accomplished in a one-pot reaction via an H-phosphonate approach. This new type of compound is expected to possess the potent antiviral and anticancer adv

Aryl H-Phosphonates. 12. Synthetic and 31P NMR Studies on the Preparation of Nucleoside H-Phosphonothioate and Nucleoside H-Phosphonodithioate Monoesters

Cieslak, Jacek,Jankowska, Jadwiga,Stawinski, Jacek,Kraszewski, Adam

, p. 7049 - 7054 (2007/10/03)

Transformation of nucleoside H-phosphonate monoesters into the corresponding H-phosphonothioate and H-phosphonodithioate derivatives and possible side-reactions that may accompany this process were studied using 31P NMR spectroscopy. These provided new insight into a possible mechanism involved in this transformation and constituted the basis for development of efficient methods for the preparation of nucleoside H-phosphonothioate and nucleoside H-phosphonodithioate monoesters using readily available H-phosphonate monoesters as starting materials.
