119-66-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 119-66-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,1 and 9 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 119-66:
(5*1)+(4*1)+(3*9)+(2*6)+(1*6)=54
54 % 10 = 4
So 119-66-4 is a valid CAS Registry Number.

Paragraph 0032; 0035; 0039; 0042; 0046; 0049, (2019/08/26)

The invention provides a preparation method, UV - 329, of an ultraviolet absorber. The method comprises the following steps: performing ammonification, diazotization, coupling, one-step reduction, two-step reduction reaction and post-treatment to prepare 2 - (2 '- hydroxyl -5' - t-octylphenyl) benzotriazole product by o-nitrochlorobenzene. To the method, by ammonia water with a concentration 10%~25%, o-nitrochlorobenzene is subjected to diazotization reaction with nitrite to generate a diazonium salt, the diazotization reaction does not need to be carried out in a strong acid medium, and byproduct ammonia water of the product in the company is comprehensively utilized. The reduction closed-loop process of the intermediate azo product adopts 2-step reduction method, the strong reducing agent is prevented from directly reducing the azo double bond to the amine, impurity generation, product purity, and yield.
