647851-43-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 647851-43-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,7,8,5 and 1 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 647851-43:
(8*6)+(7*4)+(6*7)+(5*8)+(4*5)+(3*1)+(2*4)+(1*3)=192
192 % 10 = 2
So 647851-43-2 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
