Check Digit Verification of cas no

The CAS Registry Mumber 1416985-90-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,6,9,8 and 5 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1416985-90:
(9*1)+(8*4)+(7*1)+(6*6)+(5*9)+(4*8)+(3*5)+(2*9)+(1*0)=194
194 % 10 = 4
So 1416985-90-4 is a valid CAS Registry Number.

Synthesis and antitumor activities of some 2-oxo-quinoline-3-Schiff base derivatives

Fang, Yilin,Yi, Xianghui,Qin, Wen,Zhang, Ye,Liao, Yongzhi

, p. 7449 - 7451 (2015/04/22)

A series of 2-oxo-quinoline-3-Schiff-base derivatives (4a1-4n2) have been designed and synthesized as new antitumor agents. in vitro Antitumor activities were evaluated against four cancer cell lines including MGC80-3, BEL-7404, A549 and NCI-H460. Compounds 4a1, 4a2, 4c2, 4d1, 4d2 and 4l2 exhibited better inhibition activities than commercial antitumor drug 5-fluorouracil (5-fluorouracil, IC50 = 44 ±0.54 μM) on NCI-H460, with IC50 of 35.52 ± 0.86, 16.22 ± 0.71, 11.62 ± 0.52, 5.16 ± 0.37, 7.62 ± 0.46 and 7.66 ± 0.65 μM, respectively.
