220903-34-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 220903-34-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,9,0 and 3 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 220903-34:
(8*2)+(7*2)+(6*0)+(5*9)+(4*0)+(3*3)+(2*3)+(1*4)=94
94 % 10 = 4
So 220903-34-4 is a valid CAS Registry Number.

Highly stereoselective and efficient synthesis of the dopa analogue in pepticinnamin E via enantioselective hydrogenation of dehydroamino acids

Sun, Dequn

experimental part, p. 181 - 186 (2010/09/10)

An efficient and new method was developed to prepare the dopa analogue 11 in natural pepticinnamin via catalytic hydrogenation of dehydroamino acids (DDAA) with a good yield and ee. Product 11 is a key intermediate towards the total synthesis of pepticinnamin E and its analogues. TUeBITAK.

Synthesis and in vitro evaluation of the Ras farnesyltransferase inhibitor pepticinnamin E

Hinterding, Klaus,Hagenbuch, Patrizia,Retey, Janos,Waldmann, Herbert

, p. 1236 - 1239 (2007/10/03)

A modularly built bisubstrate inhibitor, the natural product pepticinnamin E (shown on the right) was synthesized for the first time. In the case of in vitro assays it inhibits the enzyme farnesyltransferase with respect to both the peptide substrate and farnesylpyrophosohate (K1 = 30 and 8 μM, respectively). The inhibitory activity is decisively influenced by the central tripeptide unit and the absolute configuration of the non-proteinogenic amino acid incorporated therein.
