66156-71-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 66156-71-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,1,5 and 6 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 66156-71:
(7*6)+(6*6)+(5*1)+(4*5)+(3*6)+(2*7)+(1*1)=136
136 % 10 = 6
So 66156-71-6 is a valid CAS Registry Number.

Total synthesis of (+)-complanadine a using an iridium-catalyzed pyridine C-H functionalization

Fischer, Daniel F.,Sarpong, Richmond

scheme or table, p. 5926 - 5927 (2010/07/05)

The total synthesis of the Lycopodium alkaloid complanadine A, which is an unsymmetrical dimer of lycodine, was achieved by exploiting a common tetracyclic precursor. Key to the success of the synthesis was the development of a late-stage site-selective C-H functionalization of a pyridine moiety to arrive at a key boronic ester intermediate.
