Check Digit Verification of cas no

The CAS Registry Mumber 20222-80-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,2,2 and 2 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 20222-80:
(7*2)+(6*0)+(5*2)+(4*2)+(3*2)+(2*8)+(1*0)=54
54 % 10 = 4
So 20222-80-4 is a valid CAS Registry Number.

Syntheses of shuttlecock- and bowl-equipped phenylazopyridines and photomodulation of their coordination ability to Zn-porphyrin

Suwa, Kazuya,Otsuki, Joe,Goto, Kei

supporting information; experimental part, p. 2106 - 2108 (2009/07/19)

Shuttlecock- and bowl-equipped 4-(phenylazo)pyridine derivatives, which bear substituents that allow the pyridine moiety to protrude in the trans form but hinder it in the cis form, have been designed and synthesized. These molecules show cis/trans photoisomerization despite the presence of bulky substituents. 1H NMR titration with Zn-porphyrin showed that the trans isomers coordinate to Zn-porphyrin much stronger than the cis isomers.
