5140-35-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5140-35-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,4 and 0 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 5140-35:
(6*5)+(5*1)+(4*4)+(3*0)+(2*3)+(1*5)=62
62 % 10 = 2
So 5140-35-2 is a valid CAS Registry Number.

Manganese(III) acetate mediated oxidation of aporphines: a convenient and useful synthesis of oxoaporphines
Singh, Om V.,Huang, Wei-Jan,Chen, Chung-Hsiung,Lee, Shoei-Sheng
, p. 8166 - 8169 (2008/03/13)
Manganese(III) acetate mediated oxidation of aporphines to oxoaporphines is described. The developed methodology was conveniently applied for the synthesis of naturally occurring oxoaporphine alkaloids, oxoglaucine, and atheroline, starting from commercially available boldine.
