Check Digit Verification of cas no

The CAS Registry Mumber 1667-10-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,6 and 7 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1667-10:
(6*1)+(5*6)+(4*6)+(3*7)+(2*1)+(1*0)=83
83 % 10 = 3
So 1667-10-3 is a valid CAS Registry Number.

Synthesis, antimicrobial and antifungal activity of double quaternary ammonium salts of biphenyls

Ol'Khovik,Matveienko, Yu. V.,Vasilevskii,Kalechits,Zheldakova

, p. 329 - 335 (2013)

The synthetic methods for new 2-, 2,2′-, and 3-substituted 4,4′-bis(chloromethyl)biphenyls were developed. Quaternization of them with various amines resulted in a series of new double quaternary ammonium salts containing the biphenyl moiety. The majority of the obtained compounds have a pronounced antifungal and antibacterial activity against the Gram-positive bacteria.

Method for preparing biphenyl benzyl dichloride through photocatalytic chlorination

-

Paragraph 0041-0049, (2020/04/06)

The invention discloses a method for preparing biphenyl benzyl dichloride through photocatalytic chlorination. The method comprises the following steps: adding 4,4'-dimethyl biphenyl, a solvent and acatalyst into a reaction kettle, and carrying out stirring dissolution; turning on an ultraviolet lamp, and starting to introduce chlorine from the bottom; after 5 hours, monitoring the reaction process by gas chromatography, stopping the chlorine introducing when the total content of high-chlorinated products such as trichlorocompounds, tetrachlorocompounds and the like on the chromatography reaches 3%, continuously stirring for a certain time to expel residual chlorine, and then heating to evaporate out most of the solvent to obtain a crude product; and in the same reaction kettle, cooling the obtained crude product to below 40 DEG C, adding a solvent for recrystallization, continuously heating until the solvent is refluxed, completely dissolving the crude product, carrying out cooling crystallizing under stirring, filtering, and drying to obtain a white refined product.

Catalysis preparation process for 4,4'-dichloro methyl biphenyl

-

Page/Page column 4-6, (2017/08/28)

The invention discloses a catalysis preparation process for 4,4'-dichloro methyl biphenyl. The catalysis preparation process comprises the steps: putting biphenyl, hydrochloric acid with the mass fraction of 27-37% and paraformaldehyde according to the weight ratio of 1:(3-4):(0.65-0.85) into a reactor, adding a solid catalyst, then adding an organic solvent, heating up to 50-80 DEG C, introducing HCl gas, carrying out a reaction for 10-20 hours, then filtering the reaction liquid to obtain the solid catalyst, allowing the liquid to stand to separate out an acid phase, washing an organic phase with water, crystallizing, and filtering to obtain a crude product, and recrystallizing the crude product to obtain the target product 4,4'-dichloro methyl biphenyl. The preparation process provided by the invention has high conversion rate; the solid catalyst can be repeatedly used, and the catalytic efficiency is not significantly reduced after the solid catalyst is repeatedly used for 40 times.
