144629-75-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144629-75-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,6,2 and 9 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 144629-75:
(8*1)+(7*4)+(6*4)+(5*6)+(4*2)+(3*9)+(2*7)+(1*5)=144
144 % 10 = 4
So 144629-75-4 is a valid CAS Registry Number.

A novel approach to the synthesis of symmetrical and unsymmetrical porphyrin dimers
Pandey,Forsyth,Gerzevske,Lin,Smith
, p. 5315 - 5318 (2007/10/02)
Methodology for synthesis of symmetrical or unsymmetrical porphyrin dimers linked at the meso positions with phenyl or stilbene functionalities is reported; 5-porphyrinyl-dipyrromethanes are key intermediates in this approach.
