620-89-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 620-89-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,2 and 0 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 620-89:
(5*6)+(4*2)+(3*0)+(2*8)+(1*9)=63
63 % 10 = 3
So 620-89-3 is a valid CAS Registry Number.

Diarylamine Synthesis via Desulfinylative Smiles Rearrangement

Sephton, Thomas,Large, Jonathan M.,Butterworth, Sam,Greaney, Michael F.

, p. 1132 - 1135 (2022/02/09)

Diarylamines are obtained directly from sulfinamides through a novel rearrangement sequence. The transformation is transition metal-free and proceeds under mild conditions, providing facile access to highly sterically hindered diarylamines that are otherw

Sodium Butylated Hydroxytoluene: A Functional Group Tolerant, Eco-Friendly Base for Solvent-Free, Pd-Catalysed Amination

Semeniuchenko, Volodymyr,Braje, Wilfried M.,Organ, Michael G.

supporting information, p. 12535 - 12539 (2021/08/03)

NaBHT (sodium 2,6-di-tert-butyl-4-methylphenolate), a strong, but hindered and lipophilic base, has been effectively paired with similarly lipophilic, high-reactivity Pd-NHC (N-heterocyclic carbene) catalysts to produce an ideal combination for performing

Antioxidant and method for preparing antioxidant

-

Paragraph 0021; 0046; 0051; 0054; 0059; 0062; 0067, (2021/08/06)

The invention discloses an antioxidant and a method for preparing the antioxidant. An intermediate 2 reacts with an intermediate 5 to obtain an intermediate 14, the intermediate 14 isoxidized with potassium permanganate, an esterification reaction is then carried out with an intermediate 13 to obtain an intermediate 15, the intermediate 15 is reduced with tin powder to obtain an intermediate 16, the intermediate 16 and the intermediate 8 are subjected to dehydration condensation, the antioxidant is prepared, the antioxidant contains a large number of sulfur atoms, the sulfur atoms can be oxidized to form sulfoxide and sulfone compounds, the antioxidant has good oxidation resistance, free radicals generated by macromolecules can be captured, then the free radical branching reaction is inhibited, and the antioxidant activity is improved. The oxidation resistance of the high-molecular material is improved, and the self relative molecular mass is large and is not easy to separate out from the high-molecular material.
