Check Digit Verification of cas no

The CAS Registry Mumber 173903-19-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,3,9,0 and 3 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 173903-19:
(8*1)+(7*7)+(6*3)+(5*9)+(4*0)+(3*3)+(2*1)+(1*9)=140
140 % 10 = 0
So 173903-19-0 is a valid CAS Registry Number.

Paragraph 0030; 0032; 0036; 0038; 0042; 0044; 0048; 0050, (2020/07/02)

The invention belongs to the field of chemical synthesis, and relates to a novel preparation method of an indoxacarb key intermediate. In the cyclization reaction process of the key intermediate synthesis method, paraformaldehyde substances are adopted to replace original diethoxymethane, generation of by-product ethanol in the reaction process is avoided, generation of ethyl ester impurities is effectively inhibited, generation of a mixed solvent is eliminated, the environmental protection pressure is reduced, the production cost is greatly reduced while the quality of the intermediate is improved, and a good foundation is laid for production of high-quality indoxacarb.

Preparation method of indoxacarb key intermediate

Paragraph 0007; 0025-0028; 0031-0034; 0037-0040; 0043-0046, (2020/11/05)

The invention belongs to the field of chemical synthesis, and relates to a novel method for preparing an indoxacarb key intermediate. The key intermediate is 7-indeno [1, 2, e] [1, 3, 4] oxadiazine-2,4a (3H, 5H)-dicarboxylic acid-4a-methyl ester-2-benzyl ester. The preparation method is mainly characterized in that a phase transfer catalyst is added in the condensation reaction process, reactantsare in full contact under the action of the phase transfer catalyst, so that the reaction quickly realizes a homogeneous system, the reaction is more thorough, the product yield is high, the reactiontime is shortened by about 3-4 hours compared with the existing process, and the reaction rate is greatly improved. More importantly, the condensation system is a homogeneous system, is easy to dropwise add in the cyclization reaction process, does not block a bottom valve or a pipeline, is convenient to operate, saves manpower and material resources, and is beneficial to industrial production.

Visible Light-Induced Salan-Copper(II)-Catalyzed Enantioselective Aerobic α-Hydroxylation of β-Keto Esters

Yang, Fan,Zhao, Jingnan,Tang, Xiaofei,Wu, Yufeng,Yu, Zongyi,Meng, Qingwei

supporting information, p. 1673 - 1677 (2019/02/26)

A strategy of visible light-induced salan-copper(II)-catalyzed asymmetric α-hydroxylation of β-keto ester with utilization of sustainable air as the oxidant was developed. This protocol allows convenient access to a number of enantioenriched α-hydroxyl β-keto esters (up to 95% yield, 96% ee), especially for β-keto methyl esters that are valuable architectures in pharmaceuticals, including the key intermediate of the sodium-channel blocker (S)-indoxacarb. Experimental studies suggest that reactive singlet oxygen may participate in this reaction. (Figure presented.).

The invention relates to an indeno oxadiazine compound synthetic method. The method comprises the following steps: mixing toluene, methyl 5-chloro-2,3-dihydro-2-hydroxy-1-oxo-inden-2-carboxylate, benzyl carbazate and methylbenzenesulfonic acid, performing

Asymmetric α-Hydroxylation of β-Indanone Esters and β-Indanone Amides Catalyzed by C-2′ Substituted Cinchona Alkaloid Derivatives

Wang, Yakun,Yin, Hang,Qing, Hai,Zhao, Jingnan,Wu, Yufeng,Meng, Qingwei

supporting information, p. 737 - 745 (2016/03/09)

The highly catalytic asymmetric α-hydroxylation of β-indanone esters and β-indanone amides using peroxide as the oxidant was realized with a new C-2′ substituted Cinchona alkaloid derivatives. The two enantiomers of α-hydroxy-β-indanone esters could be obtained by simply changing the oxidant. This protocol allows a convenient access to the corresponding α-hydroxy-β-indanone esters and α-hydroxy-β-indanone amides with up to 99% yield and 98% ee.
