57576-41-7 Usage
Description
This noraporphindione base occurs, with liriodenine and lysicamine, in the callus tissue of Stephania cephalantha. It forms reddish crystals from EtOH and has been separated from the accompanying bases by column chromatography

Check Digit Verification of cas no
The CAS Registry Mumber 57576-41-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,5,7 and 6 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 57576-41:
(7*5)+(6*7)+(5*5)+(4*7)+(3*6)+(2*4)+(1*1)=157
157 % 10 = 7
So 57576-41-7 is a valid CAS Registry Number.

Intermolecular Benzyne Cycloaddition Approach to Aporphinoids. Total Syntheses of Norcepharadione B, Cepharadione B, Dehydroanonaine, Duguenaine, Dehydronornuciferine, Pontevedrine, O-Methylatheroline, Lysicamine, and Alkaloid PO-3

We describe a useful novel approach to the synthesis of aporphinoids, including dehydroaporphines, aristolactams, 4,5-dioxoaporphines, and 7-oxoaporphines, by means of intermolecular benzyne cycloaddition (IBC).Specifically, we report the total synthesis of the isoquinoline alkaloids norcepharadione B, cepharadione B, dehydroanonaine, deguenaine, dehydronornuciferine, pontevedrine, O-methylatheroline, lysicamine, and alkaloid PO-3.
