Check Digit Verification of cas no

The CAS Registry Mumber 84237-85-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,2,3 and 7 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 84237-85:
(7*8)+(6*4)+(5*2)+(4*3)+(3*7)+(2*8)+(1*5)=144
144 % 10 = 4
So 84237-85-4 is a valid CAS Registry Number.

An eco-friendly synthesis of 2-pyrazoline derivatives catalysed by CeCl 3· 7 H 2O

Bhat, Prabhat,Shridhar, Gomathi,Ladage, Savita,Ravishankar, Lakshmy

, p. 1441 - 1448 (2017/09/25)

Abstract: 1,3,5-triaryl-2-pyrazoline derivatives were synthesised by a condensation reaction between chalcones and phenyl hydrazine using cerium chloride heptahydrate as a catalyst. All these reactions were carried out in ethyl lactate (70%) as a green solvent. Easy and efficient work up, recyclability of solvent and catalyst are the key merits of this protocol. Graphical Abstract:: SYNOPSIS A facile protocol for the synthesis of 1,3,5-triaryl-2-pyrazolines is described. The solvent ethyl lactate, obtained from renewable sources, is biodegradable. The catalyst CeCl 3· 7 H 2O is a water-tolerant Lewis acid with low toxicity. Easy and clean work up, recyclable solvent and catalyst are merits of the protocol. The reaction works well for all systems giving good yields of the desired products.[Figure not available: see fulltext.].

Iron-catalyzed aerobic oxidative aromatization of 1,3,5-trisubstituted pyrazolines

Ananthnag, Guddekoppa S.,Adhikari, Adithya,Balakrishna, Maravanji S.

, p. 240 - 243 (2013/12/04)

A simple and high yielding method for the synthesis of tri-substituted pyrazoles via iron(III) catalyzed aerobic oxidative aromatization of pyrazolines has been reported. The process demonstrates a variety of functional group tolerance.

Antimicrobial, analgesic, DPPH scavenging activities and molecular docking study of some 1,3,5-triaryl-2-pyrazolines
