540474-57-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 540474-57-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,4,0,4,7 and 4 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 540474-57:
(8*5)+(7*4)+(6*0)+(5*4)+(4*7)+(3*4)+(2*5)+(1*7)=145
145 % 10 = 5
So 540474-57-5 is a valid CAS Registry Number.

Synthesis and optical properties of simple amine-containing conjugated polymers
Thomas III, Samuel W.,Swager, Timothy M.
, p. 2716 - 2721 (2007/10/03)
Conjugated polymers (CPs) containing amino groups have been synthesized, and their optical properties in both solution and thin film have been studied. New monomers required for the synthesis of these polymers have been readily prepared via efficient synt
