478357-64-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 478357-64-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,8,3,5 and 7 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 478357-64:
(8*4)+(7*7)+(6*8)+(5*3)+(4*5)+(3*7)+(2*6)+(1*4)=201
201 % 10 = 1
So 478357-64-1 is a valid CAS Registry Number.

Page/Page column 9, (2010/11/27)

A piezoelectric crystal element and a sensor utilizing the same are presented for use in a sensor device for identifying at least one foreign material from environment. The crystal element comprises at least one crystal resonator in the form of a inverted mesa structure, which has a membrane-like region and has a certain resonance frequency value. A surface region of the crystal resonator is modified by reactive molecules of a kind capable of interacting with the foreign material to yield a reaction product that effects a change in the resonance frequency of the crystal resonator from said certain resonance frequency value. This change is indicative of the identity and quantity of the foreign material.
