Check Digit Verification of cas no
The CAS Registry Mumber 16727-30-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,7,2 and 7 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 16727-30:
(7*1)+(6*6)+(5*7)+(4*2)+(3*7)+(2*3)+(1*0)=113
113 % 10 = 3
So 16727-30-3 is a valid CAS Registry Number.

Thermodynamics and kinetics of flavylium salts: Malvin revisited
Pina, Fernando
, p. 2109 - 2116 (1998)
The pH-dependent structural transformations in aqueous solutions of natural and synthetic flavylium salts are re-examined. The procedure uses Malvin as a reference compound and exploits the different timescales of the kinetic process that take place prior to the equilibration. For each process a kinetic expression was deduced allowing calculation of all the equilibrium constants and most of the rate constants of the system. The equilibrium constants were confirmed by comparison with the data obtained by 1H NMR. Clear evidence for the formation of significant amounts of trans-chalcone in Malvin was obtained.
