Check Digit Verification of cas no
The CAS Registry Mumber 76769-55-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,7,6 and 9 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 76769-55:
(7*7)+(6*6)+(5*7)+(4*6)+(3*9)+(2*5)+(1*5)=186
186 % 10 = 6
So 76769-55-6 is a valid CAS Registry Number.

Process for the preparation of optically active α-amino acids and their derivatives

, (2008/06/13)
A chiral α-amino acid having a hydrogen substituent in a position alpha to the carboxylic function thereof is prepared by subjecting a corresponding optical antipode with a chiral amino acid to a strong base whereby the proton in a position alpha to the carboxylic function is removed and thereafter reacting the resulting product with a chiral protonation agent.
