Check Digit Verification of cas no

The CAS Registry Mumber 53053-92-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,0,5 and 3 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 53053-92:
(7*5)+(6*3)+(5*0)+(4*5)+(3*3)+(2*9)+(1*2)=102
102 % 10 = 2
So 53053-92-2 is a valid CAS Registry Number.

Method of racemizing optically active N-acylamino acids

-

, (2008/06/13)

Optically active amino acids N-acylated with carboxylic acids are readily racemized without decomposition at elevated temperature in inert organic solvents in which they are homogeneously soluble at the racemization temperature. When the deacylated amino acid is insoluble or only sparingly soluble in the solvent, the method permits a convenient work-up of the products of enzymatic deacylation of one enantiomorph of the N-acylamino acid in which the remaining enantiomorph is racemized for recycling to the deacylation step.
