Calculate Digit Verification of CAS Registry Number 1408239-21:
(9*1)+(8*4)+(7*0)+(6*8)+(5*2)+(4*3)+(3*9)+(2*2)+(1*1)=143
143 % 10 = 3

Eklund, Emily J.,Pike, Robert D.,Scheerer, Jonathan R.

scheme or table, p. 4644 - 4647 (2012/09/08)

The diastereoselective aminoconjugate addition of benzylamine and lithiobenzylamine to both E and Z-configured vinylogous proline derivatives has been investigated. The results from this study have enabled the stereoselective synthesis of the 1-aminopyrrolizidine alkaloid (-)-absouline.
