1673-43-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1673-43-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,7 and 3 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1673-43:
(6*1)+(5*6)+(4*7)+(3*3)+(2*4)+(1*3)=84
84 % 10 = 4
So 1673-43-4 is a valid CAS Registry Number.

Synthesis and in vitro antitumor activity of 1,3,4-oxadiazole derivatives based on benzisoselenazolone

Luo, Zhen-Hua,He, Shuang-Yan,Chen, Bao-Quan,Shi, Yan-Ping,Liu, Yu-Ming,Li, Cai-Wen,Wang, Qiu-Sheng

, p. 887 - 891 (2012/08/14)

A series of novel 1,3,4-oxadiazole derivatives based on benzisoselenazolone has been prepared and tested for antiproliferative activity in vitro against the cells of human cancer cell lines: SSMC-7721 (human liver cancer cell), MCF-7 (human breast cancer cell) and A549 (human lung cancer cell). All the compounds obtained exhibited antiproliferative activity and showed selective cytotoxicity against different cancer cells. Compounds 7d and 7i showed significant antiproliferative activities against MCF-7 cells, with IC50 values of 1.07 and 1.76/μM respectively. Compound 7d were found to be the most potent compound against SSMC-7721 cells, with IC50 values 4.46/μM.
