Check Digit Verification of cas no
The CAS Registry Mumber 110553-27-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,0,5,5 and 3 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 110553-27:
(8*1)+(7*1)+(6*0)+(5*5)+(4*5)+(3*3)+(2*2)+(1*7)=80
80 % 10 = 0
So 110553-27-0 is a valid CAS Registry Number.

Paragraph 0004; 0037-0038; 0039-0040; 0041-0042; 0043-0044, (2021/07/01)
The invention relates to a synthesis method of an antioxidant 1520. According to the method, cheap diethanol amine is used as an organic amine catalyst, so that the problem of high volatility of dimethylamine is solved, and the problem that other higher amines are not easy to remove is also solved; the use of iodomethane and CuI promotes the deamination of the Mannich base and promotes the continuous conversion of the residual o-cresol, and the product has high purity and good quality. No organic solvent is added basically, waste water is little, and environmental friendliness is high; and high-voltage equipment is not used, so that the production safety coefficient is greatly improved. The method can be applied in a large scale and has wide commercial prospects.
Preparation method for antioxidant 2,4-bi(n-octyl sulfur methylene)-6-methylphenol
-
Paragraph 0030; 0031, (2016/10/17)
The invention relates to a novel preparation method for antioxidant 2,4-bi(n-octyl sulfur methylene)-6-methylphenol. Under piperidine catalysis, raw materials, namely, o-methylphenol, paraformaldehyde and octyl mercaptan react to generate antioxidant 2,4-bi(n-octyl sulfur methylene)-6-methylphenol; after the reaction, a solvent, water generated through the reaction, a catalyst and excessive unreacted raw materials are removed, and a crude product is obtained; the crude product is refined through a crystallization or cooling washing method. The product obtained through the method is colorless and is free of the disgusting smell of octyl mercaptan.
