Check Digit Verification of cas no

The CAS Registry Mumber 57572-94-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,5,7 and 2 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 57572-94:
(7*5)+(6*7)+(5*5)+(4*7)+(3*2)+(2*9)+(1*4)=158
158 % 10 = 8
So 57572-94-8 is a valid CAS Registry Number.

Method for synthesizing succinic acid compounds

-

Paragraph 0028-0036; 0040, (2019/08/01)

The invention provides a method for synthesizing succinic acid compounds. The method specifically comprises the following steps: adding a substrate, a photocatalyst and an alkali into a reaction tube,adding a reducing agent and a solvent under the atmosphere of CO2, conducting reacting under the irradiation of visible light, carrying out quenching treatment after the raw materials react completely, and then conducting separating and purifying to obtain a dicarboxylated product of olefin, namely a succinic acid compound. The photocatalyst is 4CzIPN or Ir[(ppy)2(dtbppy)]PF6 and the like, and the reaction substrate comprises 1,1-diaryl ethylene, a monoaryl substituted olefin compound, an acrylate compound and allene. According to the scheme provided by the invention, the reaction conditionsare mild, the applicability of the reaction substrate is wide, and the yield is basically not influenced under the condition that the reaction substrate is amplified to the gram scale; and meanwhile,the invention overcomes the defects of high toxicity of reagents and harsh reaction conditions in the prior art, and has a good industrial application prospect.

Cobalt-catalysed C-H carbonylative cyclisation of aliphatic amides

Williamson, Patrick,Galván, Alicia,Gaunt, Matthew J.

, p. 2588 - 2591 (2017/04/04)

A cobalt-catalysed C-H carbonylation of aliphatic carboxamide derivatives is described, employing commercially available Co(ii)-salts in the presence of a silver oxidant. This operationally simple process utilises an atmospheric pressure of CO and generates a range of substituted succinimide products bearing diverse functional groups that can be successfully accessed via this methodology.

Efficient electrochemical dicarboxylation of phenyl-substituted alkenes: Synthesis of 1-phenylalkane-1,2-dicarboxylic acids

Senboku,Komatsu,Fujimura,Tokuda

, p. 418 - 420 (2007/10/03)

Electrochemical dicarboxylation of phenyl-substituted alkenes in the presence of atmospheric pressure of carbon dioxide with a platinum plate cathode and a magnesium rod anode readily took place efficiently in a DMF solution containing 0.1 M Et4NClO4 to give the corresponding 1,2-dicarboxylic acids in high yields.

Famoxadone: The discovery and optimisation of a new agricultural fungicide

Sternberg, Jeffrey A.,Geffken, Detlef,Adams Jr., John B.,Poestages, Reiner,Sternberg, Charlene G.,Campbell, Carlton L.,Moberg, William K.

, p. 143 - 152 (2007/10/03)

Famoxadone (3-anilino-5-methyl-5-(4-phenoxyphenyl)-1,3-oxazolidine-2,4-dione), is a new agricultural fungicide recently commercialized by DuPont under the trade name Famoxate. Famoxadone is a member of a new class of oxazolidinone fungicides th

Resolution of Racemic Amines with 2-Methyl-2-phenylbutanedioic Acid

Gharpure, Milind M.,Rao, A. S.

, p. 410 - 411 (2007/10/02)

Five racemic amines were resolved in high chemical and optical yields using (S)-(+)-2-methyl-2-phenylbutanedioic acid as resolving reagent.The reagent can be recovered quantitatively and without any change in its optical purity. (R)-(-)-2-Methyl-2-phenylbutanedioic acid was also obtained.
