Check Digit Verification of cas no

The CAS Registry Mumber 84202-58-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,2,0 and 2 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 84202-58:
(7*8)+(6*4)+(5*2)+(4*0)+(3*2)+(2*5)+(1*8)=114
114 % 10 = 4
So 84202-58-4 is a valid CAS Registry Number.

Benzannelated 9-Hydroxyphenalenones

Haddon, R. C.

, p. 1733 - 1738 (2007/10/02)

The preparation and characterization of the two title compounds (6-hydroxybenzanthracen-7-one (2) and 3-hydroxybenzanthracen-4-one (3) or their proton tautomers), and an isomer (8-hydroxybenzanthracen-7-one (4)), are reported.The electronic spectra of (2) and (3) suggest that annelation of 9-hydroxyphenalenone (1) produces substantial shifts in the energies and intensities of the transitions, but does not fundamentally alter the underlying character of the chromophore.
