Check Digit Verification of cas no

The CAS Registry Mumber 328267-56-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,8,2,6 and 7 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 328267-56:
(8*3)+(7*2)+(6*8)+(5*2)+(4*6)+(3*7)+(2*5)+(1*6)=157
157 % 10 = 7
So 328267-56-7 is a valid CAS Registry Number.

A fluorescent sensor with high selectivity and sensitivity for potassium in water

He, Huarui,Mortellaro, Mark A.,Leiner, Marc J. P.,Fraatz, Robert J.,Tusa, James K.

, p. 1468 - 1469 (2003)

This communication describes a new optical sensor suitable for practical measurement of extracellular (serum or whole blood) potassium. The sensor responds rapidly and reversibly to changes in potassium concentrations typical of whole blood samples. No interferences from clinical concentrations of calcium or pH are observed, and the sodium interference is very minor. Excitation and emission occur in the visible light region. This new potassium sensor is currently used in the Roche OPTI CCA, a commercially available whole blood analyzer. Copyright
