Check Digit Verification of cas no

The CAS Registry Mumber 253878-91-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,3,8,7 and 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 253878-91:
(8*2)+(7*5)+(6*3)+(5*8)+(4*7)+(3*8)+(2*9)+(1*1)=180
180 % 10 = 0
So 253878-91-0 is a valid CAS Registry Number.

Synthesis and cytotoxicity studies of quinoline-3-carbonitrile derivatives

Zhang, Shu Lan,Zhai, Xin,Zhang, Shi Jiao,Yu, Hong Hao,Gong, Ping

scheme or table, p. 939 - 942 (2011/11/13)

A series of quinoline-3-carbonitrile derivatives were designed and synthesized. Their cytotoxicity in vitro against four cancer cell lines (A549, HT-29, MDA-MB-231 and SMMC-7721) were evaluated by standard MTT assay. The pharmacological results showed that most of the prepared compounds displayed excellent selective cytotoxicity toward SMMC-7721 cell line. Among them, compounds 7c, 7e, 11b, 11f and 11g were more active than Gefitinb against SMMC-7721 cell line.
