10283-30-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 10283-30-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,2,8 and 3 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 10283-30:
(7*1)+(6*0)+(5*2)+(4*8)+(3*3)+(2*3)+(1*0)=64
64 % 10 = 4
So 10283-30-4 is a valid CAS Registry Number.

On the Synthesis of a Phenanthrene-2,7-quinone
Hewgill, Frank R.,Slamet, Riskiono,Stewart, Jeffery M.
, p. 3033 - 3042 (2007/10/02)
Oxidative coupling of 2,2',4,4'-tetramethoxystilbene-3,3'-diol 51 gave a 51percent yield of 1,3,6,8-tetramethoxyphenanthrene-2,7-quinone 52, the first isolated example of a quinone of this type.Similar oxidation of the corresponding diphenylethane 55 gave
