Check Digit Verification of cas no
The CAS Registry Mumber 68935-26-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,9,3 and 5 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 68935-26:
(7*6)+(6*8)+(5*9)+(4*3)+(3*5)+(2*2)+(1*6)=172
172 % 10 = 2
So 68935-26-2 is a valid CAS Registry Number.

SYNTHESIS AND RESOLUTION OF NICOTINE
-
, (2016/11/28)
The present disclosure generally relates to methods of preparing nicotine and resolving R,S nicotine to enrich the (S)(?) enantiomer. The method may comprise combining N-methyl-2-pyrrolidone or a salt thereof with a nicotinate compound in the presence of a solvent and a strong base to form 1-methyl-3-nicotinoyl-2-pyrrolidone or a salt thereof; and reducing the 1-methyl-3-nicotinoyl-2-pyrrolidone or salt thereof in solution with Na2S2O4 to produce racemic nicotine or salt thereof. Resolving the racemic nicotine (or other enantiomeric mixture) may comprise combining the nicotine with (?)-O,O′-di-p-toluoyl-L-tartaric acid (L-PTTA).
