6371-55-7 Usage
General Description
The chemical 2-[4-(bis(2-hydroxyethyl)amino)phenyl]diazenylbenzoic acid, also known as Sudan IV, is an azo dye commonly used to color waxes, oils, and polishes. It is a dark red powder that is insoluble in water but soluble in organic solvents. Sudan IV is commonly employed in laboratory settings to stain lipids in biological samples, as it binds to the hydrophobic regions of lipids and other hydrophobic molecules. However, it has been classified as a carcinogen and is considered toxic if ingested or inhaled, and exposure should be carefully regulated. Sudan IV may also cause irritation to the skin, eyes, and respiratory system.Check Digit Verification of cas no
The CAS Registry Mumber 6371-55-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,3,7 and 1 respectively; the second part has 2 digits, 5 and 5 respectively.Calculate Digit Verification of CAS Registry Number 6371-55:
(6*6)+(5*3)+(4*7)+(3*1)+(2*5)+(1*5)=97
97 % 10 = 7
So 6371-55-7 is a valid CAS Registry Number.
