333405-56-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 333405-56-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,3,4,0 and 5 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 333405-56:
(8*3)+(7*3)+(6*3)+(5*4)+(4*0)+(3*5)+(2*5)+(1*6)=114
114 % 10 = 4
So 333405-56-4 is a valid CAS Registry Number.

Synthesis of a tripeptide derivative containing the Phe-Arg hydroxyethylene dipeptide isostere.
Brewer,Rich
, p. 945 - 948 (2007/10/03)
The protected hydroxyethylene dipeptide isostere of Phe-Arg and the tripeptide derivative 1 were synthesized as components of potential peptidase inhibitors. Key to the success of these syntheses is selective rhodium-catalyzed hydroboration in the presenc
