Check Digit Verification of cas no

The CAS Registry Mumber 1257883-70-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,7,8,8 and 3 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1257883-70:
(9*1)+(8*2)+(7*5)+(6*7)+(5*8)+(4*8)+(3*3)+(2*7)+(1*0)=197
197 % 10 = 7
So 1257883-70-7 is a valid CAS Registry Number.

Design, synthesis and biological evaluation of quinoline amide derivatives as novel VEGFR-2 inhibitors

Yang, Ying,Shi, Lei,Zhou, Yang,Li, Huan-Qiu,Zhu, Zhen-Wei,Zhu, Hai-Liang

supporting information; experimental part, p. 6653 - 6656 (2010/12/19)

Vascular endothelial growth factor receptor-2 (VEGFR-2) plays a crucial role in the process of cancer angiogenesis. A series of quinoline amide derivatives were prepared and found to be good inhibitors of VEGFR-2. The inhibitory activities were investigated against VEGFR-2 kinase and human umbilical vein endothelial cells (HUVEC) in vitro. Compound 6 (5-chloro-2-hydroxy-N-(quinolin-8-yl)benzamide) exhibited the most potent inhibitory activity (IC50 = 3.8 and 5.5 nM for VEGFR-2 kinase and HUVEC, respectively). Docking simulation supported the initial pharmacophoric hypothesis and suggested a common mode of interaction at the ATP-binding site of VEGFR-2, which demonstrates that compound 6 is a potential agent for cancer therapy deserving further researching.
