Check Digit Verification of cas no
The CAS Registry Mumber 4053-08-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,5 and 3 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4053-08:
(6*4)+(5*0)+(4*5)+(3*3)+(2*0)+(1*8)=61
61 % 10 = 1
So 4053-08-1 is a valid CAS Registry Number.

The quest for highly fluorescent chromophores: Evaluation of 1H,3H-isochromeno[6,5,4-mna]xanthene-1,3-dione (CXD)

, p. 53072 - 53078 (2015/02/18)
Photophysical properties of the strongly fluorescent dye, 1H,3H-isochromeno[6,5,4-mna]xanthene-1,3-dione (CXD), are reported. This highly planar, rigid dye absorbs at around 420 nm, which is ideal for excitation with a blue laser diode, and is extremely stable towards prolonged illumination. Under near-UV excitation, the dye readily sensitises free-radical polymerisation, forming a plastic film with excellent optical transparency. Weakly structured emission is observed with a small Stokes' shift and remains essentially insensitive to changes in solvent polarity. For example, in tetrahydrofuran the fluorescence quantum yield is 0.96 while the excited-singlet state lifetime is 7.4 ns. Quantum chemical calculations provide further insight into the electronic nature of the dye in solution.
