Check Digit Verification of cas no

The CAS Registry Mumber 190011-84-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,0,0,1 and 1 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 190011-84:
(8*1)+(7*9)+(6*0)+(5*0)+(4*1)+(3*1)+(2*8)+(1*4)=98
98 % 10 = 8
So 190011-84-8 is a valid CAS Registry Number.

On the Synthesis of 2-Amino-4,6-difluorobenzonitrile: Highly Selective Formation of 5-Fluoro-3-nitro-1,2-benzoquinone 2-Diazide in the Attempted Sandmeyer Cyanation of 2,4-Difluoro-6-nitrobenzenediazonium Cation

Camps, Pelayo,Morral, Jordi,Munoz-Torrero, Diego

, p. 144 - 145 (1998)

Attempted cyanation of a diazonium salt derived from 2,4-difluoro-6-nitroaniline gives 5-fluoro-3-nitro-1,2-benzoquinone 2-diazide? in good yield by selective nucleophilic substitution of the 2-fluoride group by hydroxide, instead of the desired 2-amino-4

experimental part, p. 278 - 292 (2009/10/17)

The inhibition of key receptor tyrosine kinases (RTKs) that are implicated in tumor vasculature formation and maintenance, as well as tumor progression and metastasis, has been a major focus in oncology research over the last several years. Many potent small molecule inhibitors of vascular endothelial growth factor receptor (VEGFR) and platelet-derived growth factor receptor (PDGFR) kinases have been evaluated. More recently, compounds that act through the complex inhibition of multiple kinase targets have been reported and may exhibit improved clinical efficacy. We report herein a series of potent, orally efficacious 4-amino- 3-benzimidazol-2-ylhydroquinolin-2-one analogues as inhibitors of VEGF, PDGF, and fibroblast growth factor (FGF) receptor tyrosine kinases. Compounds in this class, such as 5 (TKI258), are reversible ATP- competitive inhibitors of VEGFR-2, FGFR-1, and PDGFRβ with IC50 values 0.1 μM. On the basis of its favorable in vitro and in vivo properties, compound 5 was selected for clinical evaluation and is currently in phase I clinical trials.
