Check Digit Verification of cas no

The CAS Registry Mumber 869565-43-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,9,5,6 and 5 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 869565-43:
(8*8)+(7*6)+(6*9)+(5*5)+(4*6)+(3*5)+(2*4)+(1*3)=235
235 % 10 = 5
So 869565-43-5 is a valid CAS Registry Number.

Novel poly(2,3-diphenyl-1,4-phenylenevinylene) derivatives containing long branched alkoxy And fluorenyl substituents: Synthesis, characterization, and their applications for polymer light-emitting diodes

Chen, Kuei-Bai,Li, Hsing-Chuan,Chen, Chien-Kai,Yang, Sheng-Hsiung,Hsieh, Bing R.,Hsu, Chain-Shu

, p. 8617 - 8624 (2005)

Two series of poly(2,3-diphenyl-1,4-phenylenevinylene) (DP-PPV) derivatives containing long branched alkoxy chains or fluorenyl substituents were synthesized. The branched alkoxy groups were introduced to enhance the solubility for spin-coating processes.
