Check Digit Verification of cas no

The CAS Registry Mumber 20189-33-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,1,8 and 9 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 20189-33:
(7*2)+(6*0)+(5*1)+(4*8)+(3*9)+(2*3)+(1*3)=87
87 % 10 = 7
So 20189-33-7 is a valid CAS Registry Number.

Covalent switching, involving divinylbenzene ligands within 3D coordination polymers, indicated by changes in fluorescence

Li, Ni-Ya,Liu, Dong,Abrahams, Brendan F.,Lang, Jian-Ping

, p. 5831 - 5834 (2018)

Reversible cycloaddition reactions between 1,4-bis[2-(3-pyridyl)ethenyl]benzene and its photodimers were performed within a pair of three-dimensional coordination polymers with retention of single crystal character. In each case, switching between two crystalline forms could be followed by monitoring the flourescence behaviour.
