Check Digit Verification of cas no

The CAS Registry Mumber 128524-63-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,5,2 and 4 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 128524-63:
(8*1)+(7*2)+(6*8)+(5*5)+(4*2)+(3*4)+(2*6)+(1*3)=130
130 % 10 = 0
So 128524-63-0 is a valid CAS Registry Number.

An enantioselective approach to (-)-aphanorphine featuring a stereoselective oxidative amidation

Pansare, Sunil V.,Kulkarni, Kaivalya G.

, p. 19127 - 19134 (2013/10/22)

A formal enantioselective synthesis of (-)-aphanorphine (91% ee), that culminates with the preparation of (+)-O-methyl aphanorphine, was achieved. The methodology involves the diastereoselective synthesis of a key 3,5-disubstituted pyrrolidinone intermediate by the intramolecular oxidative amidation of a suitably functionalized α-hydroxy pentenoic acid derivative. A late-stage N-formyl protection, which functions as a latent N-methyl group, is utilized as a simple alternative to a protecting group switch and subsequent N-methylation strategy implemented in all other syntheses of aphanorphine related to the present approach. The Royal Society of Chemistry 2013.

An effective route to (-)-aphanorphine using D-tyrosine as a chiral building block

Li, Min,Zhou, Peijie,Roth, Hans F.

, p. 55 - 60 (2007/12/31)

A stereoselective approach toward a naturally occurring alkaloid, (-)-aphanorphine, has been achieved via a series of reactions from Boc-D-tyrosine. Georg Thieme Verlag Stuttgart.

Cyclic sulfamidates as lactam precursors. An efficient asymmetric synthesis of (-)-aphanorphine

Bower, John F.,Szeto, Peter,Gallagher, Timothy

, p. 5793 - 5795 (2008/02/02)

A short and efficient enantioselective synthesis of (-)-aphanorphine is described based on the use of a cyclic sulfamidate to provide a suitably functionalised lactam that allows for construction of the tricyclic 3-benzazepine scaffold. The Royal Society
