Check Digit Verification of cas no

The CAS Registry Mumber 127123-03-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,1,2 and 3 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 127123-03:
(8*1)+(7*2)+(6*7)+(5*1)+(4*2)+(3*3)+(2*0)+(1*3)=89
89 % 10 = 9
So 127123-03-9 is a valid CAS Registry Number.

Fluorescent PET (Photoinduced Electron Transfer) Sensors Selective for Submicromolar Calcium with Quantitatively Predictable Spectral and Ion-binding Properties

Silva, A. Prasanna de,Gunaratne, H. Q. Nimal

, p. 186 - 188 (1990)

The anthracene (QCa1) and pyrazoline (QCa2) derivatives display Ca2+-induced enhancements of fluorescence quantum yields (ΦF), by factors of 16 and 92, respectively; the binding selectivities (vs.Mg2+ and H+) and characteristics of the electronic (absorption and emission) spectra (except ΦFmax.) are reasonably predictable from simpler model compounds.
