214677-77-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 214677-77-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,4,6,7 and 7 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 214677-77:
(8*2)+(7*1)+(6*4)+(5*6)+(4*7)+(3*7)+(2*7)+(1*7)=147
147 % 10 = 7
So 214677-77-7 is a valid CAS Registry Number.

Synthesis and electronic spectra of substituted p-distyrylbenzenes for the use in light-emitting diodes
Stalmach, Ulf,Detert, Heiner
, p. 10 - 16 (2007/10/03)
The influence of substitution on the absorption and Luminescence spectra of oligo(phenylenevinylene)s has been studied using distyrylbenzene (DSB) as a model compound. The degree, character, and pattern of substitution was varied systematically, altering
