72853-70-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 72853-70-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,8,5 and 3 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 72853-70:
(7*7)+(6*2)+(5*8)+(4*5)+(3*3)+(2*7)+(1*0)=144
144 % 10 = 4
So 72853-70-4 is a valid CAS Registry Number.

Facile Photochemical Synthesis of Polycyclic Aromatic Compounds
Maruyama, Kazuhiro,Otsuki, Tetsuo,Mitsui, Kiichiro
, p. 1424 - 1428 (2007/10/02)
A variety of polycyclic aromatic quinones, which easily reduced to the corresponding aromatic hydrocarbons, were synthesized via one-pot photocycloaddition reaction of simple 2-halogenated 1,4-naphthoquinone derivatives with 1,1-disubstituted ethylenes.Th
