168421-94-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 168421-94-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,8,4,2 and 1 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 168421-94:
(8*1)+(7*6)+(6*8)+(5*4)+(4*2)+(3*1)+(2*9)+(1*4)=151
151 % 10 = 1
So 168421-94-1 is a valid CAS Registry Number.

Synthesis and properties of 5-(p-carbomethoxyphenyl)-15-(p-dimethylaminophenyl)porphyrin
Zindel,Lightner
, p. 1219 - 1223 (2007/10/02)
An unsymmetrically substituted 5,15-diarylporphyrin 1, with p-dimethylamino and p-carbomethoxy substituents, was synthesized via a MacDonald condensation of aryldipyrromethane precursors 6 and 12, which were prepared in good yield by three or four step pr
