1618092-89-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1618092-89-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,8,0,9 and 2 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1618092-89:
(9*1)+(8*6)+(7*1)+(6*8)+(5*0)+(4*9)+(3*2)+(2*8)+(1*9)=179
179 % 10 = 9
So 1618092-89-9 is a valid CAS Registry Number.

Controlled regioregularity in oligo(2-methoxy-5-(2′-ethylhexyloxy)-1, 4-phenylenevinylenes
Zhu, Xinju,Plunkett, Kyle N.
, p. 7093 - 7102 (2014/08/18)
A series of three pentameric derivatives of 2-methoxy-5-(2′- ethylhexyloxy)-p-phenylenevinylenes (2-4), with varying degrees of side chain regioregularity, was prepared. The oligomerization chemistry was carried out using repetitive Horner-Wadsworth-Emmon
