73501-53-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 73501-53-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,5,0 and 1 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 73501-53:
(7*7)+(6*3)+(5*5)+(4*0)+(3*1)+(2*5)+(1*3)=108
108 % 10 = 8
So 73501-53-8 is a valid CAS Registry Number.

Method for promoting synthesis of beta-hydroxyl selenide compound by visible light

-

Paragraph 0070-0073, (2021/05/01)

The invention relates to the technical field of organic synthetic chemistry, in particular to a method for promoting synthesis of a beta-hydroxyl selenide compound by visible light. The method comprises the following steps: A, sequentially adding a compound 1 and a compound 2 into a reactor; B, stirring the compound 1 and the compound 2 for reaction at a certain temperature under the irradiation of a light source under an open condition; C, after the reaction is finished, evaporating the solvent under reduced pressure to obtain a crude product; and D, carrying out column chromatography purification to obtain the beta-hydroxy selenide compound 3. According to the method, olefin and diselenide are used as raw materials, one of an acetonitrile/water mixed solvent and an acetone/water mixed solvent is used as a solvent, the reaction temperature is room temperature, and the beta-hydroxyl selenide compound is efficiently synthesized under the irradiation of a white fluorescent light source; compared with the traditional synthesis method, the method has the advantages that the reaction conditions are mild and can be smoothly carried out at room temperature; operation is simple, and all operations can be carried out in an open system; and raw materials are easy to obtain, the yield is high, functional group compatibility is good, and the substrate application range is wide.
