24786-18-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 24786-18-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,7,8 and 6 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 24786-18:
(7*2)+(6*4)+(5*7)+(4*8)+(3*6)+(2*1)+(1*8)=133
133 % 10 = 3
So 24786-18-3 is a valid CAS Registry Number.

Synthesis of benzoxazole amides as novel antifungal agents against Malassezia furfur

Kim, Beom Joon,Kim, Jinah,Kim, Young-Kook,Choi, Soon-Yong,Choo, Hea-Young Park

experimental part, p. 1270 - 1274 (2010/09/18)

Malassezia is a pathogenic fungus that causes skin diseases, such as tinea versicolor, atopic dermatitis and fatal sepsis. We report the synthesis of a series of benzoxazole amides and evaluation of their antifungal activity against Malassezia furfur. Twe

An α-hydrazinoalkylphosphonate as building block for novel N-phosphonoalkylheterocycles

Li, Zai-Guo,Sun, Hui-Kai,Wang, Qing-Min,Huang, Run-Qiu

, p. 384 - 386 (2007/10/03)

α-Hydrazinoalkylphosphonate 3 is a useful building block for the syntheses of novel N-phosphonoalkylheterocycles. N-phosphonoalkylpyrazoles 8 and 9 were prepared by the cyclization reaction of 3 with malfunctioned ethenes 5 and 6 in ethanol under reflux. N-Phosphonoalkyltriazole 10 was synthesized from 3 with N-dimethylthiomethylene benzoyl amide 4 in ethanol under reflux. The structures were confirmed by IR, 1H NMR, mass spectroscopy, and elemental analysis. At the same time, the preparation of 4 was investigated.

Reactions with N-Acylimino-dithiocarbonic-acid-diesters

Augustin, M.,Richter, M.,Salas, S.

, p. 55 - 68 (2007/10/02)

Reactions of N-acylimino-dithiocarbonic-acid-S,S-diesters 1 with nucleophilic compounds present new possibilities to synthesize heterocycles.With amines 1a reacts by mono- and disubstitution, respectively, of methylthio-groups to isothioureas 2 and guanidines 3, with 1,2-binucleophilic arenes to benzoheterocycles 4, with aliphatic diamines to imidazolines 5, pyrimidines 6, diazepines 7 and the hexamethylene-diamine-derivatives 8. 1a reacts also with hydrazines to 1,2,4-triazoles 9 and with hydrazides to the thiosemicarbazones 10 or 1,3,4-oxadiazoles 11.Heterocyclisations of 1 with guanidines, thiourea, salts of thiourea and amidines give the 1,3,5-triazines 12, 14, 15 and 16.N-benzoyl-dithiocarbonic-acid-methylester -amid reacts with CH-acidic compounds to thiazoles 17.The structures of the final products are determined by i.r.-, 1H-n.m.r.-, u.v.- and mass-spectras.
