Check Digit Verification of cas no

The CAS Registry Mumber 862794-16-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,2,7,9 and 4 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 862794-16:
(8*8)+(7*6)+(6*2)+(5*7)+(4*9)+(3*4)+(2*1)+(1*6)=209
209 % 10 = 9
So 862794-16-9 is a valid CAS Registry Number.

Galanthamine analogs: 6H-benzofuro[3a,3,2,-e,f][1]benzazepine and 6H-benzofuro[3a,3,2-e,f][3]benzazepine

Lewin, Anita H.,Szewczyk, Jerzy,Wilson, Joseph W.,Carroll, F. Ivy

, p. 7144 - 7152 (2005)

The known cholinesterase inhibitory capability of the Amarylidaceae alkaloid galanthamine prompted preparation of analogs in which the position of the nitrogen within the azepine ring is altered. The analogs 6H-benzofuro[3a,3,2-e,f][1]benzazepine and 6H-benzofuro[3a,3,2-e,f][3] benzazepine were prepared in 19 and 2.5%, respectively, following Kametani and Shimizu approaches, respectively. The aniline derivative 6H-benzofuro[3a,3,2-e, f][1]benzazepine failed to undergo most of the reactions typical for galanthamine. Thus, it neither oxidized to the analogous narwedine, nor epimerized to the analogous epigalanthamine, nor reduced to the lycoramine analog, under the conditions used for galanthamine.
