Check Digit Verification of cas no

The CAS Registry Mumber 204502-20-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,4,5,0 and 2 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 204502-20:
(8*2)+(7*0)+(6*4)+(5*5)+(4*0)+(3*2)+(2*2)+(1*0)=75
75 % 10 = 5
So 204502-20-5 is a valid CAS Registry Number.

Enhancing the proline effect: Pseudo-prolines for tailoring Cis/ trans isomerization

Keller, Michael,Sager, Cédric,Dumy, Pascal,Schutkowski, Mike,Fischer, Gunter S.,Mutter, Manfred

, p. 2714 - 2720 (1998)

Cis-trans isomerization of proline-like oxazolidines and thiazolidines, denoted pseudo-prolines, is investigated spectrophotometrically with a chymotrypsin coupled assay and by 1H NMR. A series of peptides carrying substituents of varying stere
