19982-41-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 19982-41-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,9,8 and 2 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 19982-41:
(7*1)+(6*9)+(5*9)+(4*8)+(3*2)+(2*4)+(1*1)=153
153 % 10 = 3
So 19982-41-3 is a valid CAS Registry Number.

Ultrasound-assisted, one-pot, three-component synthesis and antibacterial activities of novel indole derivatives containing 1,3,4-oxadiazole and 1,2,4-triazole moieties

Shi, Zhichuan,Zhao, Zhigang,Huang, Meiwei,Fu, Xiaolin

, p. 1320 - 1327 (2015/12/11)

Thirteen novel indole derivatives were efficiently synthesized through ultrasound irradiation by using 4-amino-5-(1H-indol-3-yl)-4H-[1,2,4]triazole-3-thiol (8) and 2-mercapto-5-substituted-1,3,4-oxadiazoles (5a-m). Compared with conventional and microwave methods, yields increased to 82-93%, and reaction times decreased to 15-35 min. The structures of these novel compounds were characterized by spectral data and elemental analysis. Two out of the synthesized compounds (10f and 10l) exhibited excellent activity against Staphylococcus aureus and Escherichia coli, and thus warrant further research.

Identification of a potent new chemotype for the selective inhibition of PDE4

Skoumbourdis, Amanda P.,Huang, Ruili,Southall, Noel,Leister, William,Guo, Vicky,Cho, Ming-Hsuang,Inglese, James,Nirenberg, Marshall,Austin, Christopher P.,Xia, Menghang,Thomas, Craig J.

, p. 1297 - 1303 (2008/09/20)

A series of substituted 3,6-diphenyl-7H-[1,2,4]triazolo[3,4-b][1,3,4]thiadiazines were prepared and analyzed as inhibitors of phosphodiesterase 4 (PDE4). Synthesis, structure-activity relationships, and the selectivity of a highly potent analogue against related phosphodiesterase isoforms are presented.
