Check Digit Verification of cas no

The CAS Registry Mumber 1330064-75-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,0,0,6 and 4 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1330064-75:
(9*1)+(8*3)+(7*3)+(6*0)+(5*0)+(4*6)+(3*4)+(2*7)+(1*5)=109
109 % 10 = 9
So 1330064-75-9 is a valid CAS Registry Number.

Synthesis of indazole based diarylurea derivatives and their antiproliferative activity against tumor cell lines

Zhao, Cui-Rong,Wang, Rui-Qi,Li, Gang,Xue, Xiao-Xia,Sun, Chang-Jun,Qu, Xian-Jun,Li, Wen-Bao

, p. 1989 - 1992 (2013/05/08)

New series of indazole based diarylureas were synthesized and their anticancer activity against cancer cells H460, A549, OS-RC-2, HT-29, Lovo, HepG2, Bel-7402, SGC-7901 and MDA-MB-231 were examined. These derivatives of diarylureas, except azaindazole based diarylureas 5f, 5l and 5m, showed superior or similar activity against most of these selected cancer cell lines to the reference compound sorafenib. The effect of substituents on the indazole ring was also investigated. Derivatives with trifluoromenthy or halogen substituent on the indazole ring showed higher activity against the selected cancer cell lines than sorafenib. The acute toxicity assay showed that compounds 5a, 5b and 5i possessed lower toxicity than sorafenib. Compound 5i with 4-(trifluoromenthy)-1H-indazole and 4-(trifluoromenthy) benzene moieties exhibited the most potent anticancer activity.
