130434-40-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 130434-40-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,4,3 and 4 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 130434-40:
(8*1)+(7*3)+(6*0)+(5*4)+(4*3)+(3*4)+(2*4)+(1*0)=81
81 % 10 = 1
So 130434-40-1 is a valid CAS Registry Number.

A New Efficient Method for the Preparation of 2-Fluoro-N-propylnorapomorphine
Berenyi, Sandor,Hosztafi, Sandor,Makleit, Sandor
, p. 2693 - 2694 (2007/10/02)
A new synthesis of the highly efficient, selective dopamine D2 agonist, 2-fluoro-N-propylnorapomorphine 1 has been accomplished, involving the transformation of thebaine 13 into 6-fluoro-6-demethoxythebaine 10, followed by sequential N-demethylation, N-alkylation, rearrangement with methanesulfonic acid into the apocodeine derivative 17, and subsequent O-demethylation with boron tribromide.
