Check Digit Verification of cas no

The CAS Registry Mumber 139-08-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,3 and 9 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 139-08:
(5*1)+(4*3)+(3*9)+(2*0)+(1*8)=52
52 % 10 = 2
So 139-08-2 is a valid CAS Registry Number.

Benzalkonium chloride preparation method

-

Paragraph 0033-0034; 0041-0044, (2019/04/26)

The invention discloses a benzalkonium chloride preparation method, which comprises: (1) carrying out a salt formation reaction on a fatty alkyl dimethyl tertiary amine and benzyl chloride in an organic solvent at a temperature of 30-70 DEG C to obtain fatty alkyl dimethyl benzyl ammonium chloride, wherein the fatty alkyl is dodecyl, tetradecyl or hexadecyl, and the organic solvent is one or a plurality of materials selected from methanol, ethanol, n-propanol, isopropanol, acetone and acetonitrile; and (2) in an organic solvent, crystallizing the mixture containing two or three fatty alkyl dimethyl benzyl ammonium chlorides prepared in the step (1). According to the present invention, the preparation method has advantages of simple process and high yield, wherein the yield can achieve morethan 90%; the content of the related substance is low, and the purity is high, and can achieve more than 99%; the water content is low; and the product has good appearance and simple post-treatment effect, can meet the requirements of various pharmacopoeia, and is suitable for the industrial production of pharmaceutical-grade benzalkonium chloride.

Benzalkonium chloride monomer synthesis technology

Paragraph 0017; 0022, (2017/09/01)

The invention relates to the technical field of fine chemicals, and more specifically relates to a benzalkonium chloride monomer synthesis technology. The synthesis technology comprises the following steps: (1) according to a formula, weighing fatty alkyl dimethyl tertiary amines, benzyl chloride, and ethyl acetate; (2) adding ethyl acetate into a glass lined reactor, pumping fatty alkyl dimethyl tertiary amines and benzyl chloride into a head tank, starting the stirring device of the reactor, dropwise adding fatty alkyl dimethyl tertiary amines and benzyl chloride into the reactor at a room temperature according to a same ratio; (3) heating the reactor to a temperature of 70 to 100 DEG C, and maintaining the temperature to carry out reactions for 7 to 10 hours; (4) starting circulating cooling water to cool the products to the room temperature until crystals are precipitated completely; (5) taking out the crystals, subjecting the crystals to vacuum suction filtration, during the suction filtration process, washing the crystals by ethyl acetate for 2 to 5 times, and saving the filter cakes; and (6) adding ethyl acetate into the filter cakes, carrying out re-crystallization, and after the crystals are completely precipitated, drying the crystals. The production cost is low and the purity of prepared benzalkonium chloride is high.
