83435-66-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83435-66-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,4,3 and 5 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 83435-66:
(7*8)+(6*3)+(5*4)+(4*3)+(3*5)+(2*6)+(1*6)=139
139 % 10 = 9
So 83435-66-9 is a valid CAS Registry Number.

PROCESS FOR THE PREPARATION OF AMIDES OF N-[1-(S)-(ETHOXYCARBONYL)-3-PHENYLPROPYL]-L-ALANINE
-
, (2015/01/07)
A process for the production of amides of N-[1-(S)-(ethoxycarbonyl)-3-phenylpropyl]-L-alanine is described. The process can be used for the production of key intermediates and finally the ACE inhibitors such as Ramipril, Enalapril, Quinapril, Trandolapril, Delapril and Moexipril starting from N-[1-(S)-(ethoxycarbonyl)-3-phenylpropyl]-L-alanine by the reaction with the appropriate amines.
