Check Digit Verification of cas no

The CAS Registry Mumber 156475-03-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,4,7 and 5 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 156475-03:
(8*1)+(7*5)+(6*6)+(5*4)+(4*7)+(3*5)+(2*0)+(1*3)=145
145 % 10 = 5
So 156475-03-5 is a valid CAS Registry Number.

Benzimidazole 2'-isonucleosides: Design, synthesis, and antiviral activity of 2-substituted-5,6-dichlorobenzimidazole 2'-isonucleosides

Freeman,Selleseth,Rideout,Harvey

, p. 155 - 174 (2007/10/03)

2,5,6-Trihalogenated benzimidazole-β-D-ribofuranosyl nucleosides and 2- substituted amino-5,6-dichlorobenzimidazole-β-L-ribofuranosyl nucleosides are potent and selective inhibitors of human cytomegalovirus (HCMV). The D- ribofuranosyl analogs are metabolized rapidly in vivo rendering them unsuitable as drug candidates. The primary source of instability is thought to be the anomeric bond. The synthesis of a series of chemically stable benzimidazole-2'-isonucleosides is presented. The synthetic schemes employed are based on nucleophilic displacements of a 2'-tosylate from carbohydrate intermediates with 2-bromo-5,6-dichlorobenzidazole. 2-Bromo and 2-isopropyl amino analogs with 3'- and 5'-oxo and deoxy substitutions were prepared. The benzimidazole-2'-isonucleosides presented here demonstrated reduced activity against HCMV when compared to other D-ribofuranosyl benzimidazole analogs. In addition, they were not found to be inhibitors of HIV.
