19726-12-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 19726-12-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,7,2 and 6 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 19726-12:
(7*1)+(6*9)+(5*7)+(4*2)+(3*6)+(2*1)+(1*2)=126
126 % 10 = 6
So 19726-12-6 is a valid CAS Registry Number.

Synthesis, structure and acetylcholinesterase inhibition activity of new diarylpyrazoles

Arshad, Iqra,Dege, Necmi,Hameed, Shahid,Kharl, Aamir Ali,Nadeem, Humaira,Naseer, Muhammad Moazzam,Paracha, Rehan Zafar,Zia, Mehwash

, (2022/02/19)

A variety of diarylpyrazole derivatives III-VI were synthesized and structurally characterized using FTIR, 1H and 13C NMR spectroscopy, and in case of compound VIb by X-ray single crystal analysis. The in vitro biological studies rev

Aurones and Analogues: Promising Heterocyclic Scaffolds for Development of Antioxidant and Antimicrobial Agents

Irshad,Ali,Iram,Ahamad,Saleem,Saadia,Batool,Kanwal,Tabassum

, p. 1519 - 1527 (2019/08/21)

Synthesis of some new multi-functional analogues of 2′-hydroxy chalcone containing isoxazole and pyrazole functions were synthesized, and their pharmacological activity was tested. Chalcone derivatives were synthesized by the reaction of 2′-hydroxy acetophenone with various substituted benzaldehydes in a basic medium. Aurones were isolated upon treatment with mercuric acetate. Synthesized chalcones and aurones were converted into the corresponding isoxazole and pyrazole derivatives upon their reaction with hydroxylamine hydrochloride or hydrazine hydrate, respectively. Structures of the compounds were confirmed by spectroscopic methods. All synthesized compounds were tested for antioxidant and antibacterial potential. Some of those demonstrated excellent antioxidant activity, and one product was identified as a promising antimicrobial candidate.

ESIPT-active organic compounds with white luminescence based on crystallization-induced keto emission (CIKE)

Liu, Huapeng,Cheng, Xiao,Zhang, Houyu,Wang, Yue,Zhang, Hongyu,Yamaguchi, Shigehiro

supporting information, p. 7832 - 7835 (2017/07/15)

Structurally simple pyrazole derivatives that exhibit excited-state intramolecular proton transfer (ESIPT) were synthesized. While these compounds displayed deep violet fluorescence in solution, in the crystalline state they showed white emission from the
