195391-98-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 195391-98-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,5,3,9 and 1 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 195391-98:
(8*1)+(7*9)+(6*5)+(5*3)+(4*9)+(3*1)+(2*9)+(1*8)=181
181 % 10 = 1
So 195391-98-1 is a valid CAS Registry Number.

Reductive diallylation of natural amino acids with triallylborane. The first synthesis of chiral 1,1-diallyl-2-amino alcohols and their cyclization into optically active pyrrolidines

Bubnov, Yuri N.,Misharin, Mikhail A.,Ignatenko, Anatoly V.

, p. 6259 - 6262 (1997)

The titled amino alcohols are obtained by treatment of chiral amino acids with triallylborane. Electrophylic iodocyclization of the alcohols leads to pyrrolidine derivatives.
