854689-14-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 854689-14-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,4,6,8 and 9 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 854689-14:
(8*8)+(7*5)+(6*4)+(5*6)+(4*8)+(3*9)+(2*1)+(1*4)=218
218 % 10 = 8
So 854689-14-8 is a valid CAS Registry Number.

Page/Page column 9, (2008/06/13)
The present invention relates to a process for the resolution of derivatives of α-amino acids. In particular the process is concerned with the resolution of a mixture of enantiomers of N-protected amino acids by crystallisation with enantiomerically pure N-unprotected β-amino acid derivatives.
