162221-97-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 162221-97-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,2,2,2 and 1 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 162221-97:
(8*1)+(7*6)+(6*2)+(5*2)+(4*2)+(3*1)+(2*9)+(1*7)=108
108 % 10 = 8
So 162221-97-8 is a valid CAS Registry Number.

Synthesis of 1,2,4-Triazoles via Oxidative Heterocyclization: Selective C-N Bond over C-S Bond Formation

Gogoi, Anupal,Guin, Srimanta,Rajamanickam, Suresh,Rout, Saroj Kumar,Patel, Bhisma K.

, p. 9016 - 9027 (2015/09/28)

The higher propensity of C-N over C-S bond forming ability was demonstrated, through formal C-H functionalization during the construction of 4,5-disubstituted 1,2,4-triazole-3-thiones from arylidenearylthiosemicarbazides catalyzed by Cu(II). However, ster

Synthesis of new 1,2,4-Triazole-5-thiones and their thioglycoside derivatives as potential antibacterial agents

Dilmaghani, Karim Akbari,Nasuhi Pur, Fazel,Jazani, Nima Hoseini,Alavi, Asma,Niknam, Zahra,Mirfakhraee, Farrin

, p. 81 - 87 (2014/01/06)

Abstract The glycosylation of 1,2,4-triazole-5-thiones has been performed with peracetylated β-pyranosyl bromide in the presence of potassium carbonate. The synthesized compounds were tested for their antimicrobial activity against bacterial (Gram-negative and Gram-positive) and yeasts strains in vitro. The synthetic compounds showed different inhibition zones against tested bacterial and yeasts strains. Among them, compounds which possessed 2-furyl and p-bromophenyl moieties showed the best results against Acinetobacter calcoaceticus ATCC 23055.

Synthesis and tuberculostatic activity of some 2-piperazinmethylene derivatives 1,2,4-triazole-3-thiones

Foks, Henryk,Janowiec, Mieczyslaw,Zwolska, Zofia,Augustynowicz-Kopec, Ewa

, p. 537 - 543 (2007/10/03)

The Mannich reaction's products of 1,2,4-triazole-3-thiones, substituted in position 4 (with ethyl, allyl, phenyl, Ph-4-Br) or 5 (with phenyl, Ph-4-OH, Ph-3,4,5-(OMe)3, 2-phenyl) were obtained. Their amino-components were 1-phenylpiperazine, 1-
