Check Digit Verification of cas no

The CAS Registry Mumber 1055039-72-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,5,5,0,3 and 9 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1055039-72:
(9*1)+(8*0)+(7*5)+(6*5)+(5*0)+(4*3)+(3*9)+(2*7)+(1*2)=129
129 % 10 = 9
So 1055039-72-9 is a valid CAS Registry Number.

New Acyclic Nucleoside Analogues. Stereospecific Synthesis of Purines and Pyrimidines Substituted with Chiral Chains by Sugar-ring Opening of &β-D-Galactopyranosyl Nucleosides

El-Kattan, Yahya,Gosselin, Gilles,Imbach, Jean-Louis

, p. 1289 - 1298 (2007/10/02)

2',3'- and 3',4'-Seco-nucleosides, retaining the carbon framework of β-D-ribofuranosyl nucleosides but having a hydroxymethyl substituent on the 4' or 5' position, have been synthesized and their antiviral properties examined.These hitherto unknown chiral acyclic nucleosides were stereospecifically prepared by ring opening of β-D-galactopyranosyl nucleosides by means of periodate oxidation followed by borohydride reduction.None of the prepared compounds showed marked antiviral effect against a variety of DNA and RNA viruses.
