Check Digit Verification of cas no

The CAS Registry Mumber 192187-30-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,2,1,8 and 7 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 192187-30:
(8*1)+(7*9)+(6*2)+(5*1)+(4*8)+(3*7)+(2*3)+(1*0)=147
147 % 10 = 7
So 192187-30-7 is a valid CAS Registry Number.

Efficient synthesis method of tipirfarnequinolinone intermediate

-

Paragraph 0022-0050, (2021/07/08)

The invention provides an efficient synthesis method of 6-(4-chlorobenzoyl)-4-(3-chlorophenyl)-3, 4-dihydro-2(1H)-quinolinone as a tipirfarneb intermediate, and belongs to the technical field of organic synthesis. The method provided by the invention comprises the following steps: in the presence of an Eaton reagent, (E)-3-(3-chlorphenyl)-N-phenylacrylamide is subjected to a ring closing reaction in a solvent to generate 4-(3-chlorphenyl)-3, 4-dihydro-2(1H)-quinolinone, then 4-chlorobenzoic acid and a metal-doped modified molecular sieve catalyst are added into a reaction system, and a Friedel-Crafts acylation reaction is performed to obtain 6-(4-chlorobenzoyl)-4-(3-chlorophenyl)-3, 4-dihydro-2(1H)-quinolinone, namely the tipirfarnequinolinone intermediate. The synthesis method provided by the invention has the advantages of high product yield, easy purification, simple post-treatment operation, and good application value, and the catalyst can be recycled and reused.
