The CAS Registry Mumber 78341-73-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,3,4 and 1 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 78341-73:
(7*7)+(6*8)+(5*3)+(4*4)+(3*1)+(2*7)+(1*3)=148
148 % 10 = 8
So 78341-73-8 is a valid CAS Registry Number.

The Nitration of Thebaine with Tetranitromethane

Allen, Robert M.,Kirby, Gordon W.,McDougall, David J.

, p. 1143 - 1147 (2007/10/02)

Thebaine (1) reacts in methanol with tetranitromethane to give, as major product, 14β-nitrocodeinone dimethyl acetal (2a), which has been converted into, inter alia, 14β-nitrocodeinone (3a), 14β-aminocodeinone dimethyl acetal (2b), 14β-aminocodeinone (3b), and 14β-aminocodeine.The nitration of thebaine with tetranitromethane in benzene in the presence of oxygen takes a different course.The major product has been identified as the cyclic peroxide 8α,10α-epidioxy-8,14-dihydro-14β-nitrothebaine (5) by a series of degradations leading to new 10α-hydroxy- and 10-oxo-thebaine derivatives.
