569-37-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 569-37-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,6 and 9 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 569-37:
(5*5)+(4*6)+(3*9)+(2*3)+(1*7)=89
89 % 10 = 9
So 569-37-9 is a valid CAS Registry Number.

Benzoyl acid ethyl ester preparation method (by machine translation)

-

Paragraph 0007; 0034-0053, (2018/05/01)

A benzoyl acid ethyl ester preparation method, characterized in that comprises the following steps: step (1): in the non-proton solvent, adding a weak inorganic base, slowly adding acetyl ethyl acetate, then dropwise benzoyl chloride reaction; step (2): add the strong inorganic base to carry out the reaction, after the reaction, filtration, shall be benzoyl ethyl acetate, the filtrate is distilled, the recovered solvent is recycled; wherein in the in the whole reaction process, does not add the aqueous reagent. The method of the whole in the preparation of waste water and gas produced, only a small amount of residue are produced, and environmental protection. Prepared by the method of the benzoyl ethyl acetate purity>94%, yield>99%, and the equipment requirement is low, and is suitable for large-scale industrial production. (by machine translation)

Decarboxylative Fluorination of Electron-Rich Heteroaromatic Carboxylic Acids with Selectfluor

Yuan, Xi,Yao, Jian-Fei,Tang, Zhen-Yu

supporting information, p. 1410 - 1413 (2017/03/23)

A transition-metal-free decarboxylative fluorination of electron-rich five-membered heteroaromatics, including furan-, pyrazole-, isoxazole-, thiophene-, indole-, benzofuran- and indazolecarboxylic acids, with Selectfluor is reported. Fluorinated dimer products were observed for nitrogen-containing heteroaromatic carboxylic acids, such as indole and pyrazole. An effective method has been developed to synthesize the monomer of 2- and 3-fluoroindoles with Li2CO3 as base at low temperature.
