139267-95-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 139267-95-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,2,6 and 7 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 139267-95:
(8*1)+(7*3)+(6*9)+(5*2)+(4*6)+(3*7)+(2*9)+(1*5)=161
161 % 10 = 1
So 139267-95-1 is a valid CAS Registry Number.

Studies on arylfuran derivatives. Part VII. Synthesis and characterization of some Mannich bases carrying halophenylfuryl moieties as promising antibacterial agents

Holla, B. Shivarama,Shivananda,Shenoy, M. Shalini,Antony, Georgy

, p. 531 - 535 (2007/10/03)

A series of 4-[5-(halophenyl)-2-furfurylidene)]amino-3-mercapto-5-substituted-1,2,4 -triazoles (3) were synthesized. Aminomethylation of 3 with formaldehyde and a secondary amine furnished Mannich bases, 4. Both Schiff bases and Mannich bases were characterized on the basis of IR, NMR, mass spectral data and elemental analysis. All the newly synthesized compounds were tested for their antibacterial activities. Some of them carrying morpholino and N-methylpiperazino residues were found to be promising antibacterial agents.
