65452-76-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 65452-76-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,4,5 and 2 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 65452-76:
(7*6)+(6*5)+(5*4)+(4*5)+(3*2)+(2*7)+(1*6)=138
138 % 10 = 8
So 65452-76-8 is a valid CAS Registry Number.

Acid-Mediated Three Component Assembly of 4-Fluoropyrazoles from α-Fluoronitroalkenes, Hydrazines, and Aldehydes

Ioffe, Sema L.,Motornov, Vladimir A.,Nelyubina, Yulia V.,Nenajdenko, Valentine G.,Tabolin, Andrey A.

, (2020/08/06)

A new approach for the synthesis of highly pharmaceutically relevant 4-fluoropyrazoles via oxidative annulation of α-fluoronitroalkenes with in situ prepared hydrazones was developed. The reaction is efficiently promoted by trifluoroacetic acid while atmo

Microwave assisted one-pot tandem three-component synthesis of 2,4,5-triary1-2-4-dihydro-3H-1,2,4-triazol-3-one derivatives

Mohammadi, Bagher,Adib, Mehdi

, p. 553 - 556 (2014/05/06)

This work described a one-pot tandem three-component synthesis of 2,4,5-triaryl-2,4-dihydro-3H-1,2,4-triazol-3-ones using a simple reaction between phenylhydrazines, benzaldehydes and phenyl isocyanates under microwave irradiation and solvent-free conditi
