Check Digit Verification of cas no

The CAS Registry Mumber 53250-83-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,2,5 and 0 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 53250-83:
(7*5)+(6*3)+(5*2)+(4*5)+(3*0)+(2*8)+(1*3)=102
102 % 10 = 2
So 53250-83-2 is a valid CAS Registry Number.

Preparation method of free radical initiator and application of free radical initiator in oxidation reaction

-

Paragraph 0027; 0030-0031; 0034-0035; 0038-0039; 0042; ..., (2021/11/06)

The invention discloses a preparation method of a free radical initiator, the preparation method comprises the following steps: feeding a hydroxylamine raw material, inorganic base and water according to a ratio, and carrying out acid-base neutralization reaction at 0-25 DEG C to dissociate hydroxylamine; adding tetrachlorophthalic anhydride, stirring at room temperature to react for 0.5-2 hours, reacting at 60-95 DEG C for 4-12 hours, washing with water, and drying at 60-80 DEG C for 10-24 hours to obtain an N-hydroxyl tetrachlorophthalimide crude product; and recrystallizing the N-hydroxyl tetrachlorophthalimide crude product in a mixed solvent of toluene and ethanol, filtering, and drying at 60-80 DEG C to obtain the N-hydroxyl tetrachlorophthalimide free radical initiator. According to the method, the adopted raw materials are simple, the conditions are easy to control, the preparation technology is green and environmentally friendly, the preparation repeatability is good, the free radical initiator is used in the oxidation reaction, a high-purity and high-yield product can be obtained, and the product obtained after repeated use still has high separation yield and purity.
