52537-82-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 52537-82-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,5,3 and 7 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 52537-82:
(7*5)+(6*2)+(5*5)+(4*3)+(3*7)+(2*8)+(1*2)=123
123 % 10 = 3
So 52537-82-3 is a valid CAS Registry Number.

Synthesis of quinazolines over recyclable Fe3O4@SiO2-PrNH2-Fe3+ nanoparticles: A green, efficient, and solvent-free protocol

Eidi, Esmaiel,Kassaee, Mohamad Z.,Nasresfahani, Zahra,Cummings, Peter T.

, (2018/09/25)

A practical and efficient method is developed for efficient synthesis of quinazoline derivatives through condensation reaction of 2-aminoaryl ketone, an aldehyde, and ammonium acetate, over magnetic Fe3O4@SiO2-PrNH2/

Recyclable, magnetic ionic liquid bmim[FeCl4]-catalyzed, multicomponent, solvent-free, green synthesis of quinazolines

Panja, Sumit Kumar,Saha, Satyen

, p. 14495 - 14500 (2013/09/02)

An atom-efficient, eco-friendly, solvent-free, high yielding, multicomponent green strategy to synthesize highly functionalized quinazoline derivatives by the one-pot reaction of 2-aminobenzophenone, aromatic aldehyde and ammonium acetate is presented. Ma

Ecofriendly and efficient one-pot procedure for the synthesis of quinazoline derivatives catalyzed by an acidic ionic liquid under aerobic oxidation conditions

Dabiri, Minoo,Salehi, Peyman,Bahramnejad, Mahboobeh

experimental part, p. 3214 - 3225 (2010/12/24)

A three-component condensation reaction between 2-aminobenzophenone derivatives, formaldehyde or aromatic aldehydes, and ammonium acetate efficiently provides substituted quinazolines in a one-pot reaction in the presence of Bronsted acidic ionic liquid, 1-methylimidazolium triflouroacetate ([Hmim]TFA), in conjunction with aerobic oxidation. The ionic liquid was separated from the reaction mixture by simple extraction and was recycled three times without considerable loss in activity. Copyright Taylor & Francis Group, LLC.
