Check Digit Verification of cas no

The CAS Registry Mumber 341-92-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,4 and 1 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 341-92:
(5*3)+(4*4)+(3*1)+(2*9)+(1*2)=54
54 % 10 = 4
So 341-92-4 is a valid CAS Registry Number.

Toll-like receptor-7 small molecule inhibitor and preparation method thereof

-

Paragraph 0130-0132, (2021/02/24)

The invention belongs to the field of chemical small molecules, and particularly relates to a Toll-like receptor-7 small molecule inhibitor. The invention provides the Toll-like receptor-7 small molecule inhibitor, which takes a co-inhibitor of TLR7 and TLR8 obtained by screening as a research object, realizes selective regulation and control of TLR7 and TLR8 through the research on the structureoptimization and structure-activity relationship (SAR) of a parent compound, and further develops a high-efficiency, non-toxic and specific small molecule inhibitor with certain selectivity on TLR 7.The TLR7 small molecule inhibitor has a certain effect and potential medicinal value in autoimmune diseases (systemic lupus erythematosus).

NH+ - F hydrogen bonding in a fluorinated "Proton Sponge" derivative: Integration of solution, solid-state, gas-phase, and computational studies

We report detailed studies on the characterization of an intramolecular NH - F hydrogen bond formed within a fluorinated "proton sponge" derivative. An ammonium ion, generated from 8-fluoro-N,N-dimethylnaphthalen-1- amine, serves as a charged hydrogen bond donor to a covalently bound fluorine appropriately positioned on the naphthalene skeleton. Potentiometric titrations of various N,N-dimethylnaphthalen-1-amines demonstrate a significant increase in basicity when hydrogen bonding is possible. X-ray crystallography reveals that NH - F hydrogen bonding in protonated 8-fluoro-N,N-di-methylnaphthalen-1-amine is heavily influenced by ion pairing in the solid state; bifurcated and trifurcated hydrogen bonds are formed depending on the counterion utilized. Compelling evidence of hydrogen bonding in the 8-fluoro-N,N-dimethylnaphthyl-1- ammonium cation is provided by gas-phase cryogenic vibrational photodissociation spectroscopy. Solution-phase infrared spectroscopy provides complementary results, and the frequencies of the N - H stretching mode in both phases are in excellent agreement with the computed vibrational spectra. NMR analysis of protonated 8-fluoro-N,N-dimethylnaphthalen-1-amine demonstrates significant H - F coupling between the N - H hydrogen and fluorine that cannot be attributed to long-range, through-bond interactions; the couplings correlate favorably with calculated values. The results obtained from these experiments are congruent with the formation of an NH - F hydrogen bond upon protonation of 8-fluoro-N,N-dimethylnaphthalen-1-amine.
