Check Digit Verification of cas no
The CAS Registry Mumber 31001-73-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,0,0 and 1 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 31001-73:
(7*3)+(6*1)+(5*0)+(4*0)+(3*1)+(2*7)+(1*3)=47
47 % 10 = 7
So 31001-73-7 is a valid CAS Registry Number.

Chromophore Specific Photoreactivity in 2,3,4-Tri(1,2-naphthoquinone-2-diazide-5-sulfonyl-oxy)-benzophenone
Schuster, C.,Bendig, J.,Neuman, K.
, p. 658 - 662 (1994)
Different electronic structures for the three 1,2-naphthoquinone-2-diazide (NQD) chromophores in 2,3,4-tri(1,2-naphthoquinone-2-diazide-5-sulfonyl-oxy)-benzophenone were detected using 1H NMR spectroscopy.The NQD substituent in the o-position of the benzophenone is influenced by intramolecular through space interactions with the benzophenone part of the molecule.The change in the electronic structure is the reason for the obtained different photoreactivity of the o-NQD chromophore compared with m-NQD and p-NQD.The relative quantum yields of photolysis are 0.3 (o-NQD) and 0.9/1.0 (m-NQD/p-NQD).
