174023-12-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 174023-12-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,4,0,2 and 3 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 174023-12:
(8*1)+(7*7)+(6*4)+(5*0)+(4*2)+(3*3)+(2*1)+(1*2)=102
102 % 10 = 2
So 174023-12-2 is a valid CAS Registry Number.

Azobenzene-porphyrins
Hunter,Hunter, Christopher A.,Sarson,Sarson, Luke D.
, p. 699 - 702 (2007/10/02)
A series of covalently-connected azobenzene-porphyrin derivatives have been synthesised and their photochemical properties investigated. The photochemistry of the porphyrin components is essentially unaltered, but photochemical isomerisation of the azobenzene components can not be detected.
