Check Digit Verification of cas no

The CAS Registry Mumber 46255-82-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,6,2,5 and 5 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 46255-82:
(7*4)+(6*6)+(5*2)+(4*5)+(3*5)+(2*8)+(1*2)=127
127 % 10 = 7
So 46255-82-7 is a valid CAS Registry Number.

Synthesis of a dihydroquinoline based merocyanine as a 'naked eye' and 'fluorogenic' sensor for hydrazine hydrate in aqueous medium and hydrazine gas

Vijay,Nandi,Samant, Shriniwas D.

, p. 30712 - 30717 (2014)

1,2,2,4-Tetramethyldihydroquinoline (TMDQ) is formylated at the 6-position and the resulting quinoline aldehyde is condensed with 3-methyl-1-phenyl-1H- pyrazol-5(4H)-one to obtain a merocyanine 6-pyrazolinyl TMDQ. The merocyanine is a selective and sensitive sensor for hydrazine hydrate in aqueous ethanolic medium and also for hydrazine gas. The merocyanine detects hydrazine hydrate selectively in less than 5 s over other amines, anions, and metals. The detection can be done simply by the naked eye and quantification can be done by absorbance/fluorescence spectroscopy. Hydrazine hydrate as well as hydrazine gas can be detected by the TLC plate technique.

Synthesis of a dihydroquinoline based fluorescent cyanine for selective, naked eye, and turn off detection of Fe3+ ions

Vijay,Nandi,Samant, Shriniwas D.

, p. 49724 - 49729 (2016/07/06)

A cyanine dye was synthesized by condensing 6-formylated 1,2,2,4-tetramethyl-1,2-dihydroquinoline (TMDQ) and 1,7-dimethyl-2-phenylimidazo[1,2-a]pyridin-1-ium iodide. The probe was a selective sensor for ferric ions in aqueous ethanolic solution. The senso

Multiple fluorescence ΔcIE and ΔrGB codes for sensing volatile organic compounds with a wide range of responses

Tian, Kaijun,Hu, Dehui,Hu, Rui,Wang, Shuangqing,Li, Shayu,Li, Yi,Yang, Guoqiang

, p. 10052 - 10054 (2011/10/31)

A highly luminescent compound, stilbene-2,4-dimethyl-6-(1,2,2,4- tetramethyl-1,2-dihydroquinolin-6-yl)-1,3,5-s-triazine (MQT), exhibits solvent polarity-induced emission enhancement. A fluorescent sensor array was fabricated with MQT and porous polymer substrates. The colorimetric changes of the array exposed to VOCs can be readily distinguished by the naked eye. Post-processing procedures proved the high selectivity of the array for VOCs. The Royal Society of Chemistry 2011.
