Check Digit Verification of cas no

The CAS Registry Mumber 1257842-84-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,7,8,4 and 2 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1257842-84:
(9*1)+(8*2)+(7*5)+(6*7)+(5*8)+(4*4)+(3*2)+(2*8)+(1*4)=184
184 % 10 = 4
So 1257842-84-4 is a valid CAS Registry Number.

Synthesis, biological evaluation, and molecular docking studies of 2-chloropyridine derivatives possessing 1,3,4-oxadiazole moiety as potential antitumor agents

Zheng, Qing-Zhong,Zhang, Xiao-Min,Xu, Ying,Cheng, Kui,Jiao, Qing-Cai,Zhu, Hai-Liang

experimental part, p. 7836 - 7841 (2011/01/13)

A series of new 2-chloropyridine derivatives possessing 1,3,4-oxadiazole moiety were synthesized. Antiproliferative assay results indicated that compounds 6o and 6u exhibited the most potent activity against gastric cancer cell SGC-7901, which was more potent than the positive control. Especially, compound 6o exhibited significant telomerase inhibitory activity (IC 50 = 2.3 ± 0.07 μM), which was comparable to the positive control ethidium bromide. Docking simulation was performed to position compound 6o into the active site of telomerase (3DU6) to determine the probable binding model.
