Check Digit Verification of cas no

The CAS Registry Mumber 320-60-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,2 and 0 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 320-60:
(5*3)+(4*2)+(3*0)+(2*6)+(1*0)=35
35 % 10 = 5
So 320-60-5 is a valid CAS Registry Number.

2,4-dichlorobenzotrifluoride preparation method

-

Paragraph 0010; 0020; 0023-0026; 0027-0038, (2020/01/14)

The invention discloses a 2,4-dichlorobenzotrifluoridepreparation method, wherein the target compound is obtained by using 2,4-dichlorotoluene as a raw material and using a mixture of cuprous chlorideand copper powder as a catalyst through a two-step reaction of chlorination and fluorination. Compared with the method in the prior art, the method of the invention has the following advantages thatthe chlorination side reactions are less, the isomer of 2,4-dichlorobenzotrifluoride cannot be generated in the reaction process, the product purity is high, the raw material sources are wide, the catalyst is low in price and convenient to recover, the production cost of the target compound is reduced, the economic benefit is increased, and environment pollution cannot be generated.

Efficient chlorination process of dichlorobenzotrifluoride

-

Paragraph 0041-0048, (2019/12/02)
