1421030-00-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1421030-00-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,1,0,3 and 0 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1421030-00:
(9*1)+(8*4)+(7*2)+(6*1)+(5*0)+(4*3)+(3*0)+(2*0)+(1*0)=73
73 % 10 = 3
So 1421030-00-3 is a valid CAS Registry Number.

Photocontrol over cooperative porphyrin self-assembly with phenylazopyridine ligands
Hirose, Takashi,Helmich, Floris,Meijer
, p. 304 - 309 (2013)
The cooperative self-assembly of chiral zinc porphyrins is regulated by a photoresponsive phenylazopyridine ligand (1; see picture). Porphyrin stacks depolymerize into dimers upon axial ligation and the strength of the coordination is regulated by its pho
