Check Digit Verification of cas no
The CAS Registry Mumber 117929-13-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,9,2 and 9 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 117929-13:
(8*1)+(7*1)+(6*7)+(5*9)+(4*2)+(3*9)+(2*1)+(1*3)=142
142 % 10 = 2
So 117929-13-2 is a valid CAS Registry Number.

Synthesis and photophysical studies of donor-acceptor substituted tetrahydropyrenes

The tetrahydropyrene derivatives 2-N,N-dimethylamino-7-nitro-4,5,9,10- tetrahydropyrene (1) and 2-N,N-dimethylamino-7-acetyl-4,5,9,10-tetrahydropyrene (2) were synthesized and characterized. Photophysical properties of these molecules were investigated in several solvents. The absorption spectrum of 1 shows a slight red shift with solvent polarity, whereas that of 2 remains more or less unchanged. Fluorescence spectra of these compounds exhibit large, solvent-polarity-dependent Stokes shifts. The Stokes shifts are correlated to ET(30) and ETN parameters and were quantitatively analyzed by the Mataga-Liptay equation. Both compounds show low fluorescence quantum yields in cyclohexane. Nanosecond flash photolysis studies suggested that the low quantum yield in cyclohexane is due to intersystem crossing to a triplet state. In the case of 2, the fluorescence quantum yields are high in all other solvents. In the case of 1 fluorescence quantum yields are very low in polar solvents and this is explained by invoking a twisted intramolecular charge transfer state.
