433226-24-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 433226-24-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,3,2,2 and 6 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 433226-24:
(8*4)+(7*3)+(6*3)+(5*2)+(4*2)+(3*6)+(2*2)+(1*4)=115
115 % 10 = 5
So 433226-24-5 is a valid CAS Registry Number.

Discovery of novel benzimidazoles as potent inhibitors of TIE-2 and VEGFR-2 tyrosine kinase receptors

We herein disclose a novel chemical series of benzimidazole-ureas as inhibitors of VEGFR-2 and TIE-2 kinase receptors, both of which are implicated in angiogenesis. Structure-activity relationship (SAR) studies elucidated a critical role for the N1 nitrogen of both the benzimidazole (segment E) and urea (segment B) moieties. The SAR results were also supported by the X-ray crystallographic elucidation of the role of the N1 nitrogen and the urea moiety when the benzimidazole-urea compounds were bound to the VEGFR-2 enzyme. The left side phenyl ring (segment A) occupies the backpocket where a 3-hydrophobic substituent was favored for TIE-2 activity.
