90833-63-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 90833-63-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,8,3 and 3 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 90833-63:
(7*9)+(6*0)+(5*8)+(4*3)+(3*3)+(2*6)+(1*3)=139
139 % 10 = 9
So 90833-63-9 is a valid CAS Registry Number.

Synthesis and evaluation of quinoxaline derivatives as potential influenza NS1A protein inhibitors

You, Lei,Cho, Eun Jeong,Leavitt, John,Ma, Li-Chung,Montelione, Gaetano T.,Anslyn, Eric V.,Krug, Robert M.,Ellington, Andrew,Robertus, Jon D.

supporting information; experimental part, p. 3007 - 3011 (2011/06/24)

A library of quinoxaline derivatives were prepared to target non-structural protein 1 of influenza A (NS1A) as a means to develop anti-influenza drug leads. An in vitro fluorescence polarization assay demonstrated that these compounds disrupted the dsRNA-NS1A interaction to varying extents. Changes of substituent at positions 2, 3 and 6 on the quinoxaline ring led to variance in responses. The most active compounds (35 and 44) had IC50 values in the range of low micromolar concentration without exhibiting significant dsRNA intercalation. Compound 44 was able to inhibit influenza A/Udorn/72 virus growth.
