854538-45-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 854538-45-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,4,5,3 and 8 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 854538-45:
(8*8)+(7*5)+(6*4)+(5*5)+(4*3)+(3*8)+(2*4)+(1*5)=197
197 % 10 = 7
So 854538-45-7 is a valid CAS Registry Number.

Highly conductive poly(phenylene thienylene)s: M-phenylene linkages are not always bad
Song, Changsik,Swager, Timothy M.
, p. 4569 - 4576 (2005)
Two isomeric polymers, which contain meta- or para-phenylene linkages between conducting segments, have been synthesized and compared by electrochemical methods. The nonconjugated poly-(1,5-diacetoxy-m-phenylene tetrathienylene) (PMPT-OAc) showed similar
