Check Digit Verification of cas no
The CAS Registry Mumber 128780-26-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,7,8 and 0 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 128780-26:
(8*1)+(7*2)+(6*8)+(5*7)+(4*8)+(3*0)+(2*2)+(1*6)=147
147 % 10 = 7
So 128780-26-7 is a valid CAS Registry Number.

Synthesis of 2,3-disubstituted norbornadienes
Tranmer, Geoffrey K.,Yip, Carol,Handerson, Sean,Jordan, Robert W.,Tam, William
, p. 527 - 535 (2000)
Various 2,3-disubstituted norbornadienes that can hardly be made by the traditional Diels-Alder method were synthesized by double lithium halide exchange of 2,3-dibromonorbornadiene in moderate to good yields.
Norbornadiene-bridged diarylethenes and their conversion into turn-off fluorescent photoswitches
Büllmann, Simon M.,J?schke, Andres
, p. 7124 - 7127 (2020/07/14)
We describe the synthesis and characterization of novel diarylethene photoswitches that contain a norbornadiene bridge and operate as p-type positive photochromes. One of the double bonds of norbornadiene is furthermore utilized to attach a fluoresceine tetrazine by an iEDDA cascade reaction, thereby forming a turn-off mode fluorescent photoswitch.

Enantiomeric discrimination in a reiterative domino coupling process: CuI-mediated Syn cyclotrimerization of racemic polycyclic trimethylstannyl bromonorbornadienes
Cossu, Sergio,Cimenti, Chiara,Peluso, Paola,Paulon, Antonio,De Lucchi, Ottorino
, p. 4086 - 4089 (2007/10/03)
The challenge to generate all-syn architecture has prompted the synthesis of syn cyclotrimers 2 from racemic bromotrimethylstannyl polycyclic alkenes 1. The syn-selective CuI-catalyzed cyclotrimerization process is both regio- and chemo-selective.
