21H,23H-Porphine, 2,3,5,7,8,12,13,15,17,18-decamethyl- is a chemical compound belonging to the porphyrin class, characterized by its unique macrocyclic structure with four pyrrole subunits interconnected by methine bridges. This specific compound features ten methyl groups attached to various positions on the porphyrin ring, which significantly influences its chemical and physical properties. It is widely recognized for its role as the core structure of heme, a vital component of hemoglobin and other biological systems, and is involved in various light-absorbing and electron-transfer processes. The decamethylated form of this porphyrin exhibits altered properties compared to its parent compound, making it a subject of interest in chemical and biological research.

Check Digit Verification of cas no

The CAS Registry Mumber 1109-22-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,0 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1109-22:
(6*1)+(5*1)+(4*0)+(3*9)+(2*2)+(1*2)=44
44 % 10 = 4
So 1109-22-4 is a valid CAS Registry Number.

Synthesis and spectra of meso-dialkyl-β-octamethylporphyrins

Zdanovich,Mamardashvili,Golubchikov

, p. 756 - 761 (2007/10/03)

Condensation of bis(3,4-dimethyl-2-pyrrolyl)methane or bis(5-carboxy-3,4-dimethyl-2-pyrrolyl)methane with unbranched aldehydes CnH2n+1CHO (n= 1-7) results in formation of 5,15-dialkyl-2,3,7,8,12,13,17,18-octamethylporphyrins. Zinc complexes of the porphyrins are obtained.
