406713-86-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 406713-86-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,6,7,1 and 3 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 406713-86:
(8*4)+(7*0)+(6*6)+(5*7)+(4*1)+(3*3)+(2*8)+(1*6)=138
138 % 10 = 8
So 406713-86-8 is a valid CAS Registry Number.

Total synthesis of (±)-stemonamide and (±)-isostemonamide
Kende, Andrew S,Martin Hernando, Jose I,Milbank, Jared B.J
, p. 61 - 74 (2007/10/03)
Two different approaches to the alkaloids stemonamide and isostemonamide using N-acyliminium chemistry are described. The approach using an aldol spirocyclization to construct the second contiguous spirocenter was successful. The total synthesis of these
