96648-50-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 96648-50-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,6,6,4 and 8 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 96648-50:
(7*9)+(6*6)+(5*6)+(4*4)+(3*8)+(2*5)+(1*0)=179
179 % 10 = 9
So 96648-50-9 is a valid CAS Registry Number.

As demonstrated in the case of N-tert.butyloxycarbonylhydroxyglycine, N-protected 2-hydroxy-2-amino acids can be directly condensed with dipeptide esters to afford tripeptide derivatives, which are activated C-terminally and transferred into the epimers (
