28463-31-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 28463-31-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,4,6 and 3 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 28463-31:
(7*2)+(6*8)+(5*4)+(4*6)+(3*3)+(2*3)+(1*1)=122
122 % 10 = 2
So 28463-31-2 is a valid CAS Registry Number.

Novel chiral synthetic path to indolizidine and quinolizidine alkaloids by means of a samarium diiodide-promoted reductive carbon-nitrogen cleavage reaction: Synthesis of (+)-(8R, 8aR)-perhydro-8-indolizidinol and (-)-deoxynupharidine

Katoh, Miho,Mizutani, Hirotake,Honda, Toshio

, p. 193 - 216 (2008/02/09)

Novel chiral synthetic procedures for indolizidine and quinolizidine alkaloids were developed, where a samarium diiodide-promoted carbon-nitrogen bond cleavage reaction was employed as a key step. Application of the procedure led to the total synthesis of (+)-(8R, 8aR)-perhydro-8-indolizidinol and (-)-deoxynupharidine.

Diels-Alder Reaction of 1-Azadienes. A Total Synthesis of Deoxynupharidine

Hwang, Yuying C.,Fowler Frank W.

, p. 2719 - 2726 (2007/10/02)

The Diels-Alder reaction of a N-acyl-1-azadiene was a key step in the total synthesis of the quinolizidine alkaloid (-)-deoxynupharidine.
