89607-34-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 89607-34-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,6,0 and 7 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 89607-34:
(7*8)+(6*9)+(5*6)+(4*0)+(3*7)+(2*3)+(1*4)=171
171 % 10 = 1
So 89607-34-1 is a valid CAS Registry Number.

Photophysical study of 6-amino-3-methyl-4-(4-nitrophenyl)-1,4-dihydropyrano[2,3-c]pyrazole-5-carbonitrile and estimation of ground-state and singlet excited-state dipole moments by solvatochromic approaches

Kumari, Rekha,Varghese, Anitha,George, Louis,K.B., Akshaya

, p. 828 - 835 (2016)

An investigation of absorption and fluorescence behaviour of 6-amino-3-methyl-4-(4-nitrophenyl)-1,4-dihydropyrano[2,3-c]pyrazole-5-carbonitrile (NDPPC) at room temperature was carried out using a series of twelve organic solvents with different polarities. Ground and excited state dipole moments were determined experimentally by using Lippert–Mataga polarity function, Bakhshiev solvent polarity parameter, Kawski-Chamma-Viallet solvent polarity parameter, Reichardt's microscopic solvent polarity parameter, Kamlet-Abboud-Taft multiple linear regression and Catalan dipolar polarizibility approach. Due to considerable π- electron density redistribution, the value of excited state dipole moment was found to be greater than that of the ground state. The ground state dipole moment value was determined by quantum chemical method which was used to estimate excited state dipole moment using solvatochromic correlations. Both non-specific solute-solvent interactions and hydrogen bonding interactions were investigated by using Kamlet-Abboud-Taft and Catalan method. TD-DFT (B3LYP/6-311G (d,p)) was used for the determination of HOMO-LUMO energies.

Nano cobalt ferrite encapsulated-silica particles bearing melamine as an easily recyclable catalyst for the synthesis of dihydropyrano[2,3-c]pyrazoles under green conditions

Dadaei, Mahla,Naeimi, Hossein

, (2021/07/10)

In this research, it was displayed an efficient method for synthesis of 6-amino-2,4-dihydropyrano[2,3-c] pyrazol-5-carbonitrile derivatives by using CoFe2O4 silica supported bearing melamine as a magnetic nanocatalyst. This nanocompo

Concentrated solar radiation-assisted one-pot/multicomponent synthesis of pyranopyrazole derivatives under neat condition

Gadkari, Yatin U.,Hatvate, Navnath T.,Telvekar, Vikas N.

, p. 4245 - 4255 (2021/07/17)

Concentrated solar radiation (CSR)-assisted synthesis of pyranopyrazole derivatives under solvent and catalyst-free condition has been reported in the present protocol. One-pot multicomponent synthesis from aromatic/heteroaldehyde, ethyl acetoacetate, malononitrile, and hydrazine hydrate leads to the final desired compounds in a good yield. This operationally simple methodology has several advantages such as green and clean reaction profile, simple workup and purification procedures, extremely short reaction time, atom efficiency, and being economical. The current energy-efficient method saves almost 98% of energy as compared to the conventional method. Graphical abstract: [Figure not available: see fulltext.]
