183370-70-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 183370-70-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,3,3,7 and 0 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 183370-70:
(8*1)+(7*8)+(6*3)+(5*3)+(4*7)+(3*0)+(2*7)+(1*0)=139
139 % 10 = 9
So 183370-70-9 is a valid CAS Registry Number.

Influence of 4′-Substitution on the Activity of Gemcitabine and Its ProTide against VZV and SARS-CoV-2

Zheng, Zihua,Groaz, Elisabetta,Snoeck, Robert,De Jonghe, Steven,Herdewijn, Piet,Andrei, Graciela

supporting information, p. 88 - 92 (2020/12/21)

In addition to its therapeutic value as a chemotherapy drug, gemcitabine is of ongoing interest to the scientific community for its broad-spectrum antiviral activity. Herein the synthesis of 4′-methoxy- and 4′-fluoro-substituted gemcitabine analogues along with their phosphoramidate prodrugs is described. Among these derivatives, 4′-fluorogemcitabine proved to be active against varicella zoster virus (VZV, TK+ strain) with an EC50 of 0.042 μM and produced significant cytotoxicity (CC50 = 0.11 μM). Upon derivatization of this trifluoro nucleoside as its prodrug, decreased anti-VZV activity was observed, but with a concomitantly improved selectivity index (SI = 36). When this prodrug was tested against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), its antiviral activity (EC50 = 0.73 μM) was comparable to or slightly lower than its cytotoxic concentration in measurements of cell growth and cell morphology, respectively.
