Check Digit Verification of cas no

The CAS Registry Mumber 118-46-7 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 8 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 118-46:
(5*1)+(4*1)+(3*8)+(2*4)+(1*6)=47
47 % 10 = 7
So 118-46-7 is a valid CAS Registry Number.

Synthesis method of 8-amino-2-naphthol

-

Paragraph 0037; 0039, (2022/02/24)

The invention relates to a synthesis method of 8-amino-2-naphthol, and belongs to the technical field of fine chemical intermediates. The method comprises the following steps: taking 2-naphthaleneboronic acid as a raw material, nitrating with acetic acid and concentrated nitric acid to obtain 8-nitro-2-naphthaleneboronic acid, reducing with iron powder or palladium on carbon, and oxidizing with hydrogen peroxide to obtain 8-amino-2-naphthol. According to the synthesis method, the problem of selectivity during nitration reaction is solved, boric acid groups are smoothly converted into hydroxyl groups again through oxidation, process conditions are relatively mild, and a high-purity product can be obtained only through recrystallization in the final reaction step.

Method for preparing adduct of butadiene polymer or copolymer and α, β-ethylenically unsaturated dicarboxylic acid compound

-

, (2008/06/13)

In a method for preparing an adduct of (A) a butadiene lower polymer or butadiene lower copolymer and (B) a α,β-ethylenically unsaturated dicarboxylic acid compound, said method is characterized in that said (A) and (B) are caused to react in the presence of one or more compounds selected from (C) p-phenylenediamine derivatives, catechol derivatives, pyrogallol derivatives, N-nitrosamines, quinoline derivatives and naphthol derivatives, thus serious increase of the viscosity of said adduct in the addition reaction can be prevented.
