Check Digit Verification of cas no

The CAS Registry Mumber 92115-05-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,1,1 and 5 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 92115-05:
(7*9)+(6*2)+(5*1)+(4*1)+(3*5)+(2*0)+(1*5)=104
104 % 10 = 4
So 92115-05-4 is a valid CAS Registry Number.

A novel indicator series for measuring pKa values in acetonitrile

Heemstra, Jennifer M.,Moore, Jeffrey S.

, p. 7287 - 7292 (2004)

A series of substituted azobenzene dyes was found to span a range of 8 pKa units in acetonitrile. The UV absorption spectra of the dyes are responsive to protonation, changing in both absorption maximum and intensity. These characteristics make the dyes useful as indicators for the measurement of pKa values of neutral organic bases that absorb in the visible region of the spectrum.
