73087-01-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 73087-01-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,0,8 and 7 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 73087-01:
(7*7)+(6*3)+(5*0)+(4*8)+(3*7)+(2*0)+(1*1)=121
121 % 10 = 1
So 73087-01-1 is a valid CAS Registry Number.

Synthesis and characterization of chiral N-O turns induced by α-aminoxy acids

Yang,Li,Ng,Yan,Qu,Wu

, p. 7303 - 7312 (2007/10/03)

Chiral α-aminoxy acids of various side chains were synthesized with high optical purity starting from chiral α-amino acids. The conformations of diamides 13a-e, 15, and 16 were probed by using NMR, FT-IR, and CD spectroscopic methods as well as X-ray crystallography. The right-handed turns with eight-membered-ring intramolecular hydrogen bonds between adjacent residues (called the N-O turns) were found to be preferred for D-aminoxy acid residues, and they were independent of the side chains. The rigid chiral N-O turns should have great potential in molecular design.
