Check Digit Verification of cas no

The CAS Registry Mumber 1228885-78-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,8,8,8 and 5 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1228885-78:
(9*1)+(8*2)+(7*2)+(6*8)+(5*8)+(4*8)+(3*5)+(2*7)+(1*8)=196
196 % 10 = 6
So 1228885-78-6 is a valid CAS Registry Number.

Design, synthesis, and in vitro antitumor evaluation of novel diaryl ureas derivatives

Sun, Min,Wu, Xiaoqing,Chen, Junqing,Cai, Jin,Cao, Meng,Ji, Min

experimental part, p. 2299 - 2306 (2010/07/05)

Two series of novel diaryl ureas have been designed and synthesized, with their in vitro antitumor effect screened on human non-small cell lung cancer (NSCLC) cell line A549 and human breast cancer cell line MDA-MB-231. Some target compounds demonstrated significant inhibitory activities against both cell lines. Compared to contrast drug Sorafenib, 1b, 1d, 1f, 1i were found to demonstrate more potent antitumor activities. The structures of all the newly synthesized compounds were determined by 1H, 13C NMR, MS, IR and elementary analysis.
