Check Digit Verification of cas no

The CAS Registry Mumber 1616578-24-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,6,5,7 and 8 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1616578-24:
(9*1)+(8*6)+(7*1)+(6*6)+(5*5)+(4*7)+(3*8)+(2*2)+(1*4)=185
185 % 10 = 5
So 1616578-24-5 is a valid CAS Registry Number.

Impact of mono- and disubstitution on the colorimetric dynamic covalent switching chalcone/flavanone scaffold

Muller, Brian M.,Mai, Jesse,Yocum, Reid A.,Adler, Marc J.

, p. 5108 - 5114 (2014)

The effect of aryl substitution on various aspects of the interconversion of ortho-hydroxychalcones and flavanones has been studied using multiple spectroscopic techniques. Derivatization of the core scaffold predictably alters the midpoint pH of this equilibration process suggesting its viability for application as a functional colorimetric molecular switch.
