34551-63-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 34551-63-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,5,5 and 1 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 34551-63:
(7*3)+(6*4)+(5*5)+(4*5)+(3*1)+(2*6)+(1*3)=108
108 % 10 = 8
So 34551-63-8 is a valid CAS Registry Number.

Solvent-free efficient one-pot synthesis of Biginelli and Hantzsch compounds catalyzed by potassium phthalimide as a green and reusable organocatalyst

Kiyani, Hamzeh,Ghiasi, Maryam

, p. 5177 - 5203 (2015/07/08)

The usage of potassium phthalimide (PPI) for the simple and green one-step multicomponent synthesis of Hantzsch 1,4-dihydropyridines, polyhydroquinolines, 3,4-dihydropyrimidin-2(1H)-ones/thiones, and octahydroquinazolinones under solventless conditions at 120°C is reported. The method is operationally simple, environmentally benign, and has relatively high yields. The other merits of this method include efficient, clean, green, and catalyst reusability.

Synthesis and 3D-QSAR study of 1,4-dihydropyridine derivatives as MDR cancer reverters

Radadiya, Ashish,Khedkar, Vijay,Bavishi, Abhay,Vala, Hardevsinh,Thakrar, Shailesh,Bhavsar, Dhairya,Shah, Anamik,Coutinho, Evans

, p. 375 - 387 (2014/02/14)

A series of symmetrical and unsymmetrical 1,4-dihydropyridines were synthesized by a rapid, single pot microwave irradiation (MWI) based protocol along with conventional approach and characterized by NMR, IR and mass spectroscopic techniques. The compound

Ionic liquid [EMIM]OAc under ultrasonic irradiation towards synthesis of 1,4-DHP's

Palakshi Reddy,Rajesh,Vijayakumar

experimental part, p. 384 - 388 (2011/10/31)

The ionic liquid 1-ethyl-3-methylimidazole acetate ([EMIM]OAc) was found to be a mild and effective catalyst for the efficient, one-pot, three-component synthesis of 1,4-dihydropyridines from arylalde-hydes, ethylacetoacetate/ acetylacetone and ammonium acetate at room temperature under sonication. The developed method has many advantages, including devoid of harmful catalysts, reacting at room temperature, higher yields in a simple methodology or operational convenience.
