42298-25-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 42298-25-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,2,9 and 8 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 42298-25:
(7*4)+(6*2)+(5*2)+(4*9)+(3*8)+(2*2)+(1*5)=119
119 % 10 = 9
So 42298-25-9 is a valid CAS Registry Number.

Oxidation of Anthracenols and Anthrone to Anthraquinones with Oxygen Mediated by Copper(II) Ion and Imidazole
Iwata, Masaaki,Kuzuhara, Hiroyoshi
, p. 1609 - 1610 (2007/10/02)
The copper(II) chloride-imidazole-ethanol system turned out to oxidize 2-anthracenols to 1,2-anthraquinones and 2-methoxy-9-anthrone to 2-methoxy-9,10-anthraquinone in practical synthetic yield.
