121839-47-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121839-47-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,8,3 and 9 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 121839-47:
(8*1)+(7*2)+(6*1)+(5*8)+(4*3)+(3*9)+(2*4)+(1*7)=122
122 % 10 = 2
So 121839-47-2 is a valid CAS Registry Number.

Synthesis of a Renin Inhibitor of the Azapeptide Type
Gante, Joachim,Kahlenberg, Harald
, p. 1085 - 1088 (2007/10/02)
The azapeptide derivative 12 is obtained in a 7-step synthesis by coupling the components 5 and 11 in the last step.Whereas the azaamino acid residue in 5 is generated by a hydrazine/isocyanate addition, the other coupling steps are done using the carbodi
