Check Digit Verification of cas no
The CAS Registry Mumber 4649-03-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,4 and 9 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4649-03:
(6*4)+(5*6)+(4*4)+(3*9)+(2*0)+(1*3)=100
100 % 10 = 0
So 4649-03-0 is a valid CAS Registry Number.

Synthesis and conformational aspects of corands incorporating pyrylium, thiopyrylium and pyridine subunits
Doddi,Ercolani,Mencarelli
, p. 1977 - 1984 (2007/10/02)
The pyrylium corands 1a, 1b and the thiopyrylium corands 2a, 2b, were prepared in good yields by heterocyclization of the macrocyclic 1,5-pentanediones 4a, 4b, whereas the pyridine corands 3a, 3b were obtained by reacting 1a and 1b, respectively, with ammonium acetate. NMR data and molecular mechanics calculations suggest that the heteroaromatic nuclei tend to fill the cavity of the macrorings.
