Check Digit Verification of cas no

The CAS Registry Mumber 180133-20-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,0,1,3 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 180133-20:
(8*1)+(7*8)+(6*0)+(5*1)+(4*3)+(3*3)+(2*2)+(1*0)=94
94 % 10 = 4
So 180133-20-4 is a valid CAS Registry Number.

Oligoanthranilamides. Non-peptide subunits that show formation of specific secondary structure

Hamuro, Yoshitomo,Geib, Steven J.,Hamilton, Andrew D.

, p. 7529 - 7541 (2007/10/03)

A family of novel oligomers based on the anthranilamide nucleus has been prepared and shown to form well-defined secondary structural features. 1H NMR and X-ray crystallographic techniques have demonstrated that intramolecular hydrogen bonds play a key role in stabilizing both linear sheet and helical conformational forms.
