10169-50-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 10169-50-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,1,6 and 9 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 10169-50:
(7*1)+(6*0)+(5*1)+(4*6)+(3*9)+(2*5)+(1*0)=73
73 % 10 = 3
So 10169-50-3 is a valid CAS Registry Number.

Rearrangements during nitrosodecarboxylation of isomeric dibromohydroxybenzoic acids

Shishkin,Fadin

, p. 688 - 692 (2008)

The reaction of 3,5-dibromo-4-hydroxybenzoic acid, its sodium salt, and also sodium 3,5-dibromo-2-hydroxybenzoate with NaNO2 in a glacial acetic acid at room temperature led to the formation of a mixture of dibromonitrophenol resulting from nitrosodecarboxylation accompanied by a rearrangement processes and followed by oxidation of the arising nitrosophenols.

3-process for the preparation of amino-salicylic acid

-

Paragraph 0029-0031, (2016/10/08)

The invention relates to a novel preparation method of 3-aminosalicylic acid. The novel preparation method is characterized in that a salicylic acid compound I as an initial raw material having a general formula shown in the description and a nitration agent undergo a reaction to produce a 3-nitrosalicylic acid compound II having a general formula shown in the description, and the 3-nitrosalicylic acid compound II undergoes nitryl catalytic hydrogenation reduction and dehalogenation hydrogenolysis reactions in the presence of an effective dose of a catalyst and hydrogen donors so that 3-aminosalicylic acid is produced.
