Check Digit Verification of cas no

The CAS Registry Mumber 1400745-52-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,0,7,4 and 5 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1400745-52:
(9*1)+(8*4)+(7*0)+(6*0)+(5*7)+(4*4)+(3*5)+(2*5)+(1*2)=119
119 % 10 = 9
So 1400745-52-9 is a valid CAS Registry Number.

Synthesis and cytotoxicity of novel ursolic acid derivatives containing an acyl piperazine moiety

Liu, Ming-Chuan,Yang, Sheng-Jie,Jin, Lin-Hong,Hu, De-Yu,Xue, Wei,Song, Bao-An,Yang, Song

, p. 128 - 135 (2013/02/23)

This study designed and synthesized a series of novel ursolic acid derivatives in an attempt to develop potent antitumor agents. Their structures were confirmed using MS, IR, 1H NMR and 13C NMR. The inhibitory activities of the title compounds against the MGC-803 (gastric cancer cell) and Bcap-37 (breast cancer cell) human cancer cell lines were evaluated using standard MTT assay in vitro. The pharmacological results showed that some of the compounds displayed moderate to high levels of antitumor activities against the tested cancer cell lines and that most exhibited more potent inhibitory activities compared with ursolic acid. The mechanism of compound 4b was preliminarily investigated by acridine orange/ethidium bromide staining, Hoechst 33258 staining, TUNEL assay and flow cytometry, which revealed that the compound can induce cell apoptosis in MGC-803 cells.
