19838-01-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 19838-01-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,8,3 and 8 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 19838-01:
(7*1)+(6*9)+(5*8)+(4*3)+(3*8)+(2*0)+(1*1)=138
138 % 10 = 8
So 19838-01-8 is a valid CAS Registry Number.

Design, solvent-free synthesis and antibacterial activity evaluation of new coumarin sulfonamides

Aminarshad, Farzaneh,Heidari, Shima,Mostajeran, Neda,Massah, Ahmad Reza

, p. 547 - 562 (2021/08/16)

A simple cost-effective and green method was presented for the synthesis of coumarin bis sulfonamides. Seventeen novel coumarin sulfonamides were synthesized in good to high yield and purity in six steps starting from 2-amino thiazole, aniline, and 4-methoxy aniline. All of the reactions have been done under green conditions without using any hazardous solvent. The chemical structures of the products were elucidated by IR, 1H NMR, and 13C NMR spectroscopy and elemental analysis. Also, the anti-bacterial properties of the synthesized sulfonamides were investigated using two strains of Staphylococcus (gram-positive) and Escherichia coli (gram-negative) bacteria.

Effect of photodynamic antibacterial chemotherapy combined with antibiotics on Gram-positive and gram-negative bacteria

Ilizirov, Yana,Formanovsky, Andrei,Mikhura, Irina,Paitan, Yossi,Nakonechny, Faina,Nisnevitch, Marina

, (2018/12/11)

The well-known and rapidly growing phenomenon of bacterial resistance to antibiotics is caused by uncontrolled, excessive and inappropriate use of antibiotics. One of alternatives to antibiotics is Photodynamic Antibacterial Chemotherapy (PACT). In the present study, the effect of PACT using a photosensitizer Rose Bengal alone and in combination with antibiotics including methicillin and derivatives of sulfanilamide synthesized by us was tested against antibiotic-sensitive and antibiotic-resistant clinical isolates of Gram-positive S. aureus and Gram-negative P. aeruginosa. Antibiotic-sensitive and resistant strains of P. aeruginosa were eradicated by Rose Bengal under illumination and by sulfanilamide but were not inhibited by new sulfanilamide derivatives. No increase in sensitivity of P. aeruginosa cells to sulfanilamide was observed upon a combination of Rose Bengal and sulfanilamide under illumination. All tested S. aureus strains (MSSA and MRSA) were effectively inhibited by PACT. When treated with sub-MIC concentrations of Rose Bengal under illumination, the minimum inhibitory concentrations (MIC) of methicillin decreased significantly for MSSA and MRSA strains. In some cases, antibiotic sensitivity of resistant strains can be restored by combining antibiotics with PACT.
