7131-09-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7131-09-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,1,3 and 1 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 7131-09:
(6*7)+(5*1)+(4*3)+(3*1)+(2*0)+(1*9)=71
71 % 10 = 1
So 7131-09-1 is a valid CAS Registry Number.

Preparation and application of thiosemicarbazone compound

-

Paragraph 0010; 0012-0013, (2021/02/20)

The invention discloses a thiosemicarbazone compound, and biological activity analysis is carried out on the thiosemicarbazone compound. The invention also discloses application of the thiosemicarbazone compound in preparation of antibacterial drugs. According to the invention, important intermediates 6a-6h are synthesized from hydrazine hydrate and react with adamantane benzaldehyde respectivelyto synthesize eight adamantane aromatic aldehyde thiosemicarbazone compounds, the structures of the compounds can be confirmed by infrared, nuclear magnetic hydrogen spectrum, carbon spectrum and massspectrum methods, and the antibacterial activity of the compounds is tested in vitro. The result shows that the compound has a good antibacterial effect on escherichia coli and bacillus subtilis.
