175090-76-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 175090-76-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,5,0,9 and 0 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 175090-76:
(8*1)+(7*7)+(6*5)+(5*0)+(4*9)+(3*0)+(2*7)+(1*6)=143
143 % 10 = 3
So 175090-76-3 is a valid CAS Registry Number.

Synthesis of 2,3-disubstituted 1,4-naphthoquinones as antiplatelet agents

Lien, Jin-Cherng,Wu, Chi-Rei,Hour, Mann-Jen,Huang, Li-Jiau,Huang, Tur-Fu,Kuo, Sheng-Chu

, p. 639 - 644 (2008)

In continuing search for novel antiplatelet agents, the highly potent agent 2-chloro-3-methoxycarbonylethylcarboxamido-1,4-naphthoquinone 2 was selected as lead compound. Structureactivity relationships in this series were examined. Some of these compound

Synthesis and cytotoxicity of 1,2-disubstituted naphth[2,3-d]imidazole-4,9-diones and related compounds

Kuo, Sheng-Chu,Ibuka, Toshiro,Huang, Li-Jiau,Lien, Jin-Cherng,Yean, Shyue-Ren,Huang, Shung-Chieh,Lednicer, Daniel,Morris-Natsehke, Susan,Lee, Kuo-Hsiung

, p. 1447 - 1451 (2007/10/03)

As part of our continuing search for potential anticancer drug candidates that are selective against slowly growing solid tumors, we have synthesized several series of 1- and 2-substituted derivatives of the lead structure, 1-ethyl-2-methylnaphth[2,3-d]midazole-4,9-dione (5). Their cytotoxic activity in the National Cancer Institute's in vitro cancer cell line panel is reported. In general, substitution of various alkyl, phenyl, or benzyl moieties did not improve activity, and compound 5 remains the most active naphth[2,3-d]imidazole-4,9-dione derivative. However, high levels of activity and selectivity were found with several related 2-(acylamino)-3-chloro1,4-naphthoquinones (2f-j). Compound 2i, 2-[(2-fluorophenyl)acetamido]-3-chloro-1,4-naphthoquinone, has been selected for further in vivo testing and as an additional lead compound for further structural modification.
