Check Digit Verification of cas no

The CAS Registry Mumber 52289-25-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,2,8 and 9 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 52289-25:
(7*5)+(6*2)+(5*2)+(4*8)+(3*9)+(2*2)+(1*5)=125
125 % 10 = 5
So 52289-25-5 is a valid CAS Registry Number.

Conformational studies by dynamic NMR. 84.1 Structure, conformation, and stereodynamics of the atropisomers of N-aryl-tetrahydropyrimidines

Garcia,Grilli,Lunazzi,Mazzanti,Orelli

, p. 6679 - 6684 (2001)

The existence of stereolabile atropisomers for a number of N-aryl-tetrahydropyrimidines in solution has been deduced from the observation of the anisochronous NMR signals of prochiral methylene groups. The interconversion barriers for these atropisomers h
