Check Digit Verification of cas no

The CAS Registry Mumber 128796-39-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,7,9 and 6 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 128796-39:
(8*1)+(7*2)+(6*8)+(5*7)+(4*9)+(3*6)+(2*3)+(1*9)=174
174 % 10 = 4
So 128796-39-4 is a valid CAS Registry Number.

Biphenyl compound, liquid crystal composition containing biphenyl compound and application thereof

-

Paragraph 0201-0205, (2021/05/01)

The invention relates to a biphenyl compound, a liquid crystal composition containing the biphenyl compound and an application thereof. Specifically, the invention discloses a biphenyl compound of which the structure is shown as a formula I, and the definition is shown in the specification in detail. The invention further discloses the liquid crystal composition. The liquid crystal composition at least comprises one or more compounds in a compound shown as a formula I. The liquid crystal composition has improved physical parameters, such as higher dielectric constant anisotropy, higher optical anisotropy, lower rotary viscosity and the like, has the advantages of realizing quick response, reducing energy consumption, improving image quality and the like, and is suitable for a liquid crystal display in an IPS mode.

Magnesium promoted autocatalytic dehydrogenation of amine borane complexes: A reliable, non-cryogenic, scalable access to boronic acids

Marciasini, Ludovic D.,Richard, Jimmy,Cacciuttolo, Bastien,Sartori, Guillaume,Birepinte, Melodie,Chabaud, Laurent,Pinet, Sandra,Pucheault, Mathieu

, p. 164 - 171 (2018/12/05)

Owing to the unusual reactivity of dialkylamine-borane complexes, a methodology was developed to simply access boronic acids. The intrinsic instability of magnesium aminoborohydride was tweaked into a tandem dehydrogenation borylation sequence. Proceeding via an autocatalytic cycle, amineborane dehydrogenation was induced by a variety of Grignard reagents. Overall, addition of the organomagnesium species onto specially designed dialkylamine-borane complexes led to a variety of boronic acids in high yields. In addition, the reaction can be performed under Barbier conditions, on a large scale.

Photoinduced Miyaura Borylation by a Rare-Earth-Metal Photoreductant: The Hexachlorocerate(III) Anion

Qiao, Yusen,Yang, Qiaomu,Schelter, Eric J.

supporting information, p. 10999 - 11003 (2018/07/31)

The first photoinduced carbon(sp2)–heteroatom bond forming reaction by a rare-earth-metal photoreductant, a Miyaura borylation, has been achieved. This simple, scalable, and novel borylation method that makes use of the hexachlorocerate(III) anion ([CeIIICl6]3?, derived from CeCl3) has a broad substrate scope and functional-group tolerance and can be conducted at room temperature. Combined with Suzuki–Miyaura cross-coupling, the method is applicable to the synthesis of various biaryl products, including through the use of aryl chloride substrates.
