Check Digit Verification of cas no

The CAS Registry Mumber 1269992-25-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,9,9,9 and 2 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1269992-25:
(9*1)+(8*2)+(7*6)+(6*9)+(5*9)+(4*9)+(3*2)+(2*2)+(1*5)=217
217 % 10 = 7
So 1269992-25-7 is a valid CAS Registry Number.

Nicotinic acid-supported cobalt ferrite-catalyzed one-pot synthesis of substituted chromeno[3,4-b]quinolines

Foroughi Kaldareh, Mahdiye,Mokhtary, Masoud,Nikpassand, Mohammad

, (2020/01/25)

One-pot synthesis of substituted chromeno[3,4-b]quinoline derivatives was developed by three-component reaction of aldehydes, dimedone or 1,3-cyclohexadione, and 4-aminocoumarin in the presence of nicotinic acid-supported cobalt ferrite [CoFe2O

High quantum yield and pH sensitive fluorescence dyes based on coumarin derivatives: Fluorescence characteristics and theoretical study

Hua, Chao-Jun,Zhang, Kan,Xin, Ming,Ying, Ting,Gao, Jian-Rong,Jia, Jian-Hong,Li, Yu-Jin

, p. 49221 - 49227 (2016/06/09)

The fluorescence coumarin derivatives were synthesized by an efficient one-pot, three-component reaction in 80-90% yields. These fluorescence dyes exhibited high fluorescent intensity and quantum yield where compound 4e, with p-methyl substituted on the phenyl ring, had the maximum fluorescence intensity and also the fluorescence quantum yield reached 0.83. These coumarin derivatives display different fluorescence in acidity and alkaline conditions and the fluorescent colour changed from blue to yellow-green when the pH of the solution turned from acidic to alkaline. The pH sensitive fluorescence properties of the coumarin derivatives showed a large shift from 441 to 538 nm in wavelength. Experimental results were confirmed with DFT and TDDFT calculations.

Facile one-pot synthesis of chromeno[4,3-b] quinoline derivatives catalyzed by Cu(II)-Schiff base/SBA-15

Motamedi, Radineh,Bardajee, Ghasem Rezanejade,Shakeri, Somaye

, p. 181 - 184 (2014/07/07)

A novel, one-pot, simple, environmentally benign and efficient protocol has been employed for the synthesis of chromeno[4,3-b]quinoline derivatives in the presence of catalytic amounts of Cu(II)-Schiff base/SBA-15 under solvent-free conditions in excellen

Design, synthesis and evaluation of cytotoxicity of novel chromeno[4,3-b]quinoline derivatives

, p. 111 - 118 (2011/09/19)

In the present work 15 new 1,4-dihydropyridines (DHPs) bearing a coumarin ring were synthesized and assessed on 4 different human cancer cell lines (HeLa, K562, LS180, and MCF-7). Although, all the derivatives were inactive on LS180 cell line, the results
