839711-82-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 839711-82-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,3,9,7,1 and 1 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 839711-82:
(8*8)+(7*3)+(6*9)+(5*7)+(4*1)+(3*1)+(2*8)+(1*2)=199
199 % 10 = 9
So 839711-82-9 is a valid CAS Registry Number.

Stereoselective synthesis of swainsonines from pyridines
Heimg?rtner, Gerres,Raatz, Dirk,Reiser, Oliver
, p. 643 - 655 (2007/10/03)
An efficient synthesis of (-)-swainsonine and (-)-2,8a-di-epi-swainsonine was developed starting from readily available 2-pyridinecarbaldehyde and 3-hydroxypyridine. In particular, it was demonstrated that the mixture of simple indolizidines, i.e. lentigi
