The CAS Registry Mumber 1643447-99-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,4,3,4,4 and 7 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1643447-99:
(9*1)+(8*6)+(7*4)+(6*3)+(5*4)+(4*4)+(3*7)+(2*9)+(1*9)=187
187 % 10 = 7
So 1643447-99-7 is a valid CAS Registry Number.

Palladium(ii)-catalysed total synthesis of naturally occurring pyrano[3,2-a]carbazole and pyrano[2,3-b]carbazole alkaloids

Hesse, Ronny,Jaeger, Anne,Schmidt, Arndt W.,Knoelker, Hans-Joachim

, p. 3866 - 3876 (2014/06/09)

Seven naturally occurring pyranocarbazole alkaloids (pyrayafoline A-E, O-methylmurrayamine A and O-methylmahanine) have been obtained by total synthesis using a palladium(ii)-catalysed oxidative cyclisation of a diarylamine to an orthogonally diprotected 2,7-dihydroxycarbazole as key step. This journal is the Partner Organisations 2014.
