1620900-75-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1620900-75-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,0,9,0 and 0 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1620900-75:
(9*1)+(8*6)+(7*2)+(6*0)+(5*9)+(4*0)+(3*0)+(2*7)+(1*5)=135
135 % 10 = 5
So 1620900-75-5 is a valid CAS Registry Number.

SnO nanoparticles as an efficient catalyst for the one-pot synthesis of chromeno[2,3-b]pyridines and 2-amino-3,5-dicyano-6-sulfanyl pyridines

Safaei-Ghomi, Javad,Shahbazi-Alavi, Hossein,Heidari-Baghbahadorani, Elham

, p. 50668 - 50677 (2014)

SnO nanoparticles have been used as an efficient catalyst for the preparation of chromeno[2,3-b]pyridines and 2-amino-3,5-dicyano-6-sulfanyl pyridines under reflux conditions in ethanol in good to excellent yields. This flexible and nano-catalytic procedure showed good recyclability and provides a clean condensation reaction in a short reaction time. This journal is

Chitosan functionalized by citric acid: an efficient catalyst for one-pot synthesis of 2,4-diamino-5H-[1]benzopyrano[2,3-b]pyridine-3-carbonitriles 5-(arylthio) or 5-[(arylmethyl)thio] substituted

Chitosan (CS) functionalized by citric acid has been used as an efficient catalyst for the preparation of 2,4-diamino-5H-[1]benzopyrano[2,3-b]pyridine-3-carbonitriles 5-(arylthio) or 5-[(arylmethyl)thio] substituted by a multicomponent reaction of salicyl

Highly efficient synthesis of benzopyranopyridines via ZrP 2O 7 nanoparticles catalyzed multicomponent reactions of salicylaldehydes with malononitrile and thiols

Safaei-Ghomi, Javad,Kiani, Marzieh,Ziarati, Abolfazl,Shahbazi-Alavi, Hossein

, p. 450 - 457 (2014/06/10)

ZrP2O7 nanoparticles as an efficient catalyst have been used for the preparation of benzopyrano[2,3-b]pyridines from the four-component condensation reaction of salicylalde-hydes, thiols, and 2 equiv. of malononitrile under reflux co
