Check Digit Verification of cas no
The CAS Registry Mumber 78597-54-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,5,9 and 7 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 78597-54:
(7*7)+(6*8)+(5*5)+(4*9)+(3*7)+(2*5)+(1*4)=193
193 % 10 = 3
So 78597-54-3 is a valid CAS Registry Number.

Two series comprising 20 novel benzenesulfonamides bearing thioureido-linked pyrazole 8 and amino-1,2,4-thiadiazole 10 were synthesized and assayed as human carbonic anhydrase (hCA) inhibitors against isoforms I and II as well as the tumor-associated isof
Synthesis of Aminopyrazoles from Isoxazoles: Comparison of Preparative Methods by in situ NMR Analysis

A single-step method and a two-step method for the synthesis of aminopyrazoles from isoxazoles are presented and compared. Based on in situ NMR monitoring, both processes proceed through a ketonitrile. In the single-step process, hydrazine serves to both open the isoxazole to the unisolated ketonitrile intermediate and form the aminopyrazole. The two-step process involves ring opening of the isoxazole by deprotonation with hydroxide to generate the ketonitrile followed by the addition of acetic acid and hydrazine to form the aminopyrazole.
Study of regioselectivity of reactions between 3(5)-aminopyrazoles and 2-acetylcycloalkanones

, p. 1111 - 1120 (2013/01/15)
Regioselectivity was examined of reactions between nine 3(5)-aminopyrazoles and 2-acetylcyclopentanone and 2-acetylcyclohexanone under various conditions. A series of cyclopenta[e]pyrazolo-[1,5-a]pyrimidines was obtained. The highest regioselectivity of the reaction was observed in alcohol at 20°C in the presence of a catalytic quantity of trifl uoroacetic acid. The regiostructure of compounds was established by 1H and 13C NMR spectroscopy. Pleiades Publishing, Ltd., 2012.
