Check Digit Verification of cas no

The CAS Registry Mumber 947243-86-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,7,2,4 and 3 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 947243-86:
(8*9)+(7*4)+(6*7)+(5*2)+(4*4)+(3*3)+(2*8)+(1*6)=199
199 % 10 = 9
So 947243-86-9 is a valid CAS Registry Number.

Ring B functionalization of scalarane sesterterpenes by radical relay halogenation

Kulci?ki, Veaceslav,Ungur, Nicon,Gavagnin, Margherita,Castelluccio, Francesco,Cimino, Guido

, p. 7617 - 7623 (2007)

The functionalization of the B-ring of the scalarane framework has been achieved for the first time by a radical relay halogenation (RRH) synthetic method. The known scalaranic methyl ester, which was prepared by a procedure with an overall yield higher than those reported in the literature, has been used as the starting substrate. Some theoretical considerations explaining the course of RRH reaction are also presented.
