545432-91-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 545432-91-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,4,5,4,3 and 2 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 545432-91:
(8*5)+(7*4)+(6*5)+(5*4)+(4*3)+(3*2)+(2*9)+(1*1)=155
155 % 10 = 5
So 545432-91-5 is a valid CAS Registry Number.

Bisfunctionalized m-phenylene ethynylene imine oligomers were polymerized in the polar solvent acetonitrile, resulting in high-molecular weight poly(m-phenylene ethynylene imine)s. It is hypothesized that this polymerization, which proceeds through the re
