145593-71-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 145593-71-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,5,9 and 3 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 145593-71:
(8*1)+(7*4)+(6*5)+(5*5)+(4*9)+(3*3)+(2*7)+(1*1)=151
151 % 10 = 1
So 145593-71-1 is a valid CAS Registry Number.

Investigation of the kinetics of degradation of hexopyranosylated cytosine nucleosides using liquid chromatography

Thoithi, Grace N.,Van Schepdael, Ann,Busson, Roger,Janssen, Gerard,Van Aerschot, Arthur,Herdewijn, Piet,Roets, Eugene,Hoogmartens, Jos

, p. 189 - 203 (2007/10/03)

Liquid chromatography was used to follow the degradation of hexopyranosylated cytosine nucleosides in buffers of acid, neutral and alkaline pH and of constant ionic strength. The compounds were found to degrade by hydrolysis to cytosine and/or by deamination to the corresponding uracil nucleosides. Degradation in acid is influenced by the number of sugar hydroxyl groups, presence of sugar double bonds and the type of anomer. Stability of some of the compounds was compared with that of related thymine nucleosides. Temperature studies support a unimolecular mechanism of hydrolysis at pH 1.22.
