934710-77-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 934710-77-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,3,4,7,1 and 0 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 934710-77:
(8*9)+(7*3)+(6*4)+(5*7)+(4*1)+(3*0)+(2*7)+(1*7)=177
177 % 10 = 7
So 934710-77-7 is a valid CAS Registry Number.

Novel daidzein analogs and their in vitro anti-influenza activities

Chung, Shu-Ting,Huang, Yi-Ting,Hsiung, Hsin-Yi,Huang, Wen-Hsin,Yao, Chen-Wen,Lee, An-Rong

, p. 685 - 696 (2015/04/27)

A series of novel isoflavonoids were synthesized based on structural modifications of daidzein, an active ingredient of traditional Chinese medicine (TCM) and evaluated for their anti-influenza activity, in vitro, against H1N1 Tamiflu-resistant (H1N1 TR) virus in the MDCK cell line. Among them, 4-oxo-4H-1-benzopyran-8-carbaldehydes 11a-11g were most promising, and they demonstrated better activities and selectivities comparable to those the reference ribarivin, a nucleoside antiviral agent. 3-(4-Bromophenyl)-7-hydroxy-4-oxo-4H-1-benzopyran-8-carboxaldehyde (11c) displayed the best inhibitory activity (EC50, 29.0 μM) and selectivity index (SI>10.3). Analysis of the structure￡activity relationships (SAR) indicated that both the non-naturally-occurring Br-substituted B-ring and appropriate CHO and OH groups on the A-ring might be critical for the activity and selectivity against H1N1 TR influenza viruses.

Azaheterocyclic derivatives of α-pyrono[2,3-f]isoflavones

Shokol,Turov,Semenyuchenko,Khilya

, p. 668 - 672 (2008/02/08)

9-Azahetaryl-3-arylpyrano[2,3-f]chromen-4,8-diones were synthesized by condensation of 7-hydroxy-8-formylisoflavones with 2-azahetarylacetonitriles followed by acid hydrolysis.
