Check Digit Verification of cas no

The CAS Registry Mumber 82080-39-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,0,8 and 0 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 82080-39:
(7*8)+(6*2)+(5*0)+(4*8)+(3*0)+(2*3)+(1*9)=115
115 % 10 = 5
So 82080-39-5 is a valid CAS Registry Number.

An effective strategy to tune supramolecular interaction via a spiro-bridged spacer in oligothiophene-S,S-dioxides and their anomalous photoluminescent behavior

Xie, Ling-Hai,Hou, Xiao-Ya,Hua, Yu-Ran,Huang, Yan-Qin,Zhao, Bao-Min,Liu, Feng,Peng, Bo,Wei, Wei,Huang, Wei

We demonstrate that incorporating nonplanar spiro-bridged structures is an effective strategy for tuning supramolecular interactions of optoelectronic functional moieties. In the model compounds spiro-bridged oligothiophene-S,S- dioxides (BSiSDTFO), unusual dimers constructed by spiro-bridged spacers do not form excimers, which is confirmed by crystallographic data and fluorescent emission spectra.
