Uses
Octamethylporphyrin was readily obtained from ethyl 3,4,5-trimethylpyrrole-2-carboxylate. Steric control can be overridden by apparent electronic effect is demonstrated by the even bulkier pyrrole derivative, ethyl 3,4,5-trimethylpyrrole-2-carboxylate. The reaction with diazonium salts of theEthyl 3,4,5-trimethylpyrrole-2-carboxylatehas been examined in detail by chromatographic and spectroscopic methods. In the presence of a strong mineral acid, Ethyl 3,4,5-trimethylpyrrole-2-carboxylate reacts with p-nitrobenzenediazonium ions to give a red, chemically labile, azo dye.
Check Digit Verification of cas no
The CAS Registry Mumber 2199-46-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,9 and 9 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 2199-46:
(6*2)+(5*1)+(4*9)+(3*9)+(2*4)+(1*6)=94
94 % 10 = 4
So 2199-46-4 is a valid CAS Registry Number.
