23912-79-0 Usage
General Description
5,7,12,14-Pentacenetetrone, also known as anthrarobin, is a chemical compound with the molecular formula C14H8O4. It is a yellow powder that is insoluble in water and most organic solvents. 5,7,12,14-Pentacenetetrone is used in the production of dyes and pigments, specifically for the coloration of textiles and hair. It is also utilized as a medicinal agent for the treatment of skin conditions such as psoriasis and eczema, due to its anti-inflammatory and antiproliferative properties. However, 5,7,12,14-Pentacenetetrone may have potential mutagenic and carcinogenic effects, and caution should be exercised in its handling and use.
Check Digit Verification of cas no
The CAS Registry Mumber 23912-79-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,9,1 and 2 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 23912-79:
(7*2)+(6*3)+(5*9)+(4*1)+(3*2)+(2*7)+(1*9)=110
110 % 10 = 0
So 23912-79-0 is a valid CAS Registry Number.
