Calculate Digit Verification of CAS Registry Number 433735-02:
(8*4)+(7*3)+(6*3)+(5*7)+(4*3)+(3*5)+(2*0)+(1*2)=135
135 % 10 = 5
So 433735-02-5 is a valid CAS Registry Number.

A new stereocontrolled synthesis of uncommon tripeptides derived from 2,6-diaminopimelic acid (2,6-DAP)

Paradisi, Francesca,Porzi, Gianni,Sandri, Sergio

, p. 3319 - 3324 (2001)

The stereocontrolled synthesis of uncommon tripeptides 8 and 11a-c, structural variants of 2,6-diaminopimelic acid, was carried out starting from the mono-lactim ether 1 easily obtained from L-valine. The configurations of the introduced stereogenic centers were assigned on the basis of 1H NMR spectroscopic data.
