Check Digit Verification of cas no
The CAS Registry Mumber 69963-21-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,9,6 and 3 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 69963-21:
(7*6)+(6*9)+(5*9)+(4*6)+(3*3)+(2*2)+(1*1)=179
179 % 10 = 9
So 69963-21-9 is a valid CAS Registry Number.

Method for synthesizing chiral nicotine from butyrolactone
-
Paragraph 0054; 0057; 0060, (2021/11/03)
The invention discloses a method for synthesizing chiral nicotine from butyrolactone. The fumarates and γ - butyrolactone are condensed under the action of a basic catalyst to yield 4 - chloro -1 - (3 - pyridine) -1 -butanone by reaction with hydrochloric acid and reacted with a chlorination reagent to produce (- B -) S (-4 -1 -dichlorobutyl) pyridine which is reacted with an amine reagent under basic conditions to give (-3 -) -1 -methyl nicotine and (S)-3 - nicotinic acetylbutanolamines obtained by the reaction with the aminating reagent under an alkaline condition to produce a chiral hydroxy S S group - (1) S- methylnicotine or a (4 -) S nicotinic acid. The application can determine whether a methylation reaction is needed according to the type of amination reagent. The yield of (S)- nicotine was high.
