Check Digit Verification of cas no

The CAS Registry Mumber 261762-56-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,1,7,6 and 2 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 261762-56:
(8*2)+(7*6)+(6*1)+(5*7)+(4*6)+(3*2)+(2*5)+(1*6)=145
145 % 10 = 5
So 261762-56-5 is a valid CAS Registry Number.

Preparation method of 2-fluorine-3-chlorophenol

-

Paragraph 0041-0045; 0047-0048; 0050-0051; 0053-0054; 0056, (2021/01/15)

The invention discloses a preparation method of 2-fluorine-3-chlorophenol, and relates to the technical field of fine chemical engineering. The method comprises the following steps: by taking 2, 4-dichloro-3-fluoronitrobenzene as a raw material, firstly carrying out etherification to prepare 2-alkoxy-3-fluorine-4-chloronitrobenzene or 2-chlorine-3-fluorine-4-alkoxy nitrobenzene, then reducing into2-alkoxy-3-fluorine-4-chloraniline or 2-chlorine-3-fluorine-4-alkoxy aniline, and then carrying out diazo reduction reaction to remove amino, to prepare 2-fluorine-3-chlorobenzene ether, and performing one-step cracking to prepare 2-fluorine-3-chlorophenol. The method has the advantages that the total yield is 60%, the product purity is 98% or above, and the method is easy for industrial production.
