Check Digit Verification of cas no

The CAS Registry Mumber 203916-59-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,9,1 and 6 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 203916-59:
(8*2)+(7*0)+(6*3)+(5*9)+(4*1)+(3*6)+(2*5)+(1*9)=120
120 % 10 = 0
So 203916-59-0 is a valid CAS Registry Number.

Halogen Bonding Directed Supramolecular Quadruple and Double Helices from Hydrogen-Bonded Arylamide Foldamers

Liu, Chuan-Zhi,Koppireddi, Satish,Wang, Hui,Zhang, Dan-Wei,Li, Zhan-Ting

, p. 226 - 230 (2019)

Halogen bonding has been used to glue together hydrogen-bonded short arylamide foldamers to achieve new supramolecular double and quadruple helices in the solid state. Three compounds, which bear a pyridine at one end and either a CF2I or fluor

Paragraph 0039; 0040; 0041, (2016/10/09)

PROBLEM TO BE SOLVED: To provide an active pharmaceutical ingredient that is useful as MEK inhibitors and is stable physicochemically. SOLUTION: The present invention provides an educt I-type crystal of 3,4-difluoro-2-(2-fluoro-4-iodo-phenyl amino)-n-(2-hydroxy-ethoxy)-5-(3-oxo-[1,2]oxazinan-2-ylmethyl)-benzamide, having peaks with diffraction angles expressed by 2θ of 14.9, 16.9 and 23.1° (±0.2°) in a powder X-ray diffraction pattern measured using Cu Kα(1.54060?) as an X-ray source.

Design and synthesis of novel allosteric MEK inhibitor CH4987655 as an orally available anticancer agent

scheme or table, p. 1795 - 1801 (2011/05/11)

The MAP kinase pathway is one of the most important pathways involved in cell proliferation and differentiation, and its components are promising targets for antitumor drugs. Design and synthesis of a novel MEK inhibitor, based on the 3D-structural information of the target enzyme, and then multidimensional optimization including metabolic stability, physicochemical properties and safety profiles were effectively performed and led to the identification of a clinical candidate for an orally available potent MEK inhibitor, CH4987655, possessing a unique 3-oxo-oxazinane ring structure at the 5-position of the benzamide core structure. CH4987655 exhibits slow dissociation from the MEK enzyme, remarkable in vivo antitumor efficacy both in mono- and combination therapy, desirable metabolic stability, and insignificant MEK inhibition in mouse brain, implying few CNS-related side effects in human. An excellent PK profile and clear target inhibition in PBMC were demonstrated in a healthy volunteer clinical study.

Beyond the MEK-pocket: Can current MEK kinase inhibitors be utilized to synthesize novel type III NCKIs? Does the MEK-pocket exist in kinases other than MEK?

scheme or table, p. 226 - 229 (2009/05/26)

An approach and preliminary results for utilizing legacy MEK inhibitors as templates for a reiterative structural based design and synthesis of novel, type III NCKIs (non-classical kinase inhibitors) is described. Evidence is provided that the MEK-pocket

A process for producing 2,3,4-trifluoro-5-(iodo or bromo)benzoic acid, the process comprising a haloganation step in which 2,3,4-trifluorobenzoic acid is iodinated or brominated directly with an iodinating agent or brominating agent in a reaction solvent

Extensive halogen scrambling and buttressing effects encountered upon treatment of oligobromoarenes with bases

Mongin, Florence,Marzi, Elena,Schlosser, Manfred

, p. 2771 - 2777 (2007/10/03)

As a rule, tri-, tetra- and pentahaloarenes readily undergo ortho-lithiation when treated with amide-type bases. However, halogen migration occurs whenever the substrate contains three or more contiguous halogen atoms, provided that at least one of them is bromine or iodine. Dismutation and reduction processes often take place concomitantly. In this manner, a variety of organometallic intermediates may be formed, the driving force always being a decrease in basicity. When no such energy gain can be achieved, a sterically crowded substrate may just turn out to be inert; this was found to be the case with 1,5-dibromo-3-fluoro-2-(trimethylsilyl)benzene, 1,5-dibromo-3-fluoro-2,4-bis(trimethylsilyl)benzene, and 1,5-dibromo-3-fluoro-2,4-diiodobenzene. Buttressing effects are apparently strong enough to prevent expedient deprotonation of those substrates.
