111042-61-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 111042-61-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,0,4 and 2 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 111042-61:
(8*1)+(7*1)+(6*1)+(5*0)+(4*4)+(3*2)+(2*6)+(1*1)=56
56 % 10 = 6
So 111042-61-6 is a valid CAS Registry Number.

Screening of biological activities of a series of chalcone derivatives against human pathogenic microorganisms

Karaman, Isa,Gezegen, Hayreddin,Guerdere, M. Burcu,Dingil, Alparslan,Ceylan, Mustafa

experimental part, p. 400 - 408 (2010/09/04)

In an effort to develop new antimicrobial agents, a series of chalcone derivatives, 3-60, were prepared by Claisen-Schmidt condensation of appropriate acetophenones and 2-furyl methyl ketones with appropriate aromatic aldehydes, furfural, and thiophene-2-carbaldehyde in an aqueous solution of NaOH and EtOH at room temperature. The synthesized compounds were characterized by means of their IR- and NMR-spectral data, and elemental analysis. All compounds were tested for their antibacterial and antifungal activities by the disc diffusion method. For the most active compounds, also minimum inhibitory concentrations (MICs) were determined.
