The CAS Registry Mumber 91586-47-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,5,8 and 6 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 91586-47:
(7*9)+(6*1)+(5*5)+(4*8)+(3*6)+(2*4)+(1*7)=159
159 % 10 = 9
So 91586-47-9 is a valid CAS Registry Number.

Inverse Electron Demand Diels-Alder Reactions of 3-Carbomethoxy-2-pyrones. Controlled Introduction of Oxygenated Aromatics: Benzene, Phenol, Catechol, Resorcinol, and Pyrogallol Annulation. Regiospecific Total Synthesis of Sendaverine and a Preparation of 6,7-Benzomorphans

Boger, Dale B.,Mullican, Michael D.

, p. 4033 - 4044 (2007/10/02)

A full investigation of the preparation and Diels-Alder reactions of 3-carbomethoxy-2-pyrones is described.Methods for the preparation of a full range of oxygen-substituted aromatics: benzene, 1-, 2-, or 3-phenol, symmetrical or unsymmetrical o-catechol, resorcinol, and pyrogallol annulation from a common 3-carbomethoxy-2-pyrone intermediate are detailed.A regiospecific total synthesis of sendaverine, a 2-benzyltetrahydroisoquinoline possessing a selectively protected, symmetrical o-catechol, and a preparation of 6,7-benzomorphans are described.
