Check Digit Verification of cas no
The CAS Registry Mumber 93765-84-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,7,6 and 5 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 93765-84:
(7*9)+(6*3)+(5*7)+(4*6)+(3*5)+(2*8)+(1*4)=175
175 % 10 = 5
So 93765-84-5 is a valid CAS Registry Number.

Paragraph 0046-0047; 0068-0069, (2021/03/31)
The invention belongs to the field of organic synthesis, and particularly relates to a preparation method of 4-halogenated -3-fluorotoluene. The preparation reaction of 4-halogenated -3-fluorotolueneshown as a formula (I) is shown in the specification. According to the method, halogenation reaction is conducted on 3-fluorotoluene serving as an initial raw material to obtain a halide, and hydrogenreduction is conducted to obtain a compound shown in the general formula (I), wherein X is chlorine or bromine. According to the method, 3-fluorotoluene is used as a raw material, and a target product is obtained through two-step reactions of halogenation and reduction. The reaction steps in the process are few; diazotization, nitrification and other reactions are avoided, and the reaction safetyis high.
