339546-21-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 339546-21-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,9,5,4 and 6 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 339546-21:
(8*3)+(7*3)+(6*9)+(5*5)+(4*4)+(3*6)+(2*2)+(1*1)=163
163 % 10 = 3
So 339546-21-3 is a valid CAS Registry Number.

PROCESSES FOR THE RECOVERY OF OPTICALLY ACTIVE DIACYLTARTATIC ACIDS

-

Page/Page column 7-8, (2008/06/13)

When a salt of an amine and an optically active diacyltartaric acid, or a diastereomer salt of an optically active amine and an optically active diacyltartaric acid, obtained by optically resolving a racemic amine using the optically active diacyltartaric acid, is salt-exchanged with an acid aqueous solution, the optically active diacyltartaric acid is added in the acid aqueous solution beforehand. Furthermore, a raw material containing a racemic amine and an optically active diacyltartaric acid is optically resolved, and the diastereomer salt of the optically active amine and the optically active diacyltartaric acid respectively of one isomer type, is separated. The obtained diastereomer salt is dissociated using an acid aqueous solution containing the optically active diacyltartaric acid, for recovering the optically active diacyltartaric acid, and the obtained' optically active diacyltartaric acid is recycled into an optical resolution step as a raw material of the optical resolution step.
