557085-67-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 557085-67-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,5,7,0,8 and 5 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 557085-67:
(8*5)+(7*5)+(6*7)+(5*0)+(4*8)+(3*5)+(2*6)+(1*7)=183
183 % 10 = 3
So 557085-67-3 is a valid CAS Registry Number.

High carrier mobility in a series of new semiconducting PPV-type polymers
Krebs, Frederik C.,Jorgensen, Mikkel
, p. 4374 - 4384 (2007/10/03)
The synthesis and characterization of a series of semiconducting polymers of the polyphenylenevinylene (PPV) type is presented. These new polymers have every second phenylene ring substituted by two alkyl groups of equal length which are hexyl, heptyl, oc
