62637-98-3 Usage
General Description
2-(Phenylazo)-1-naphthalenol acetate, also known as Sudan IV, is a synthetic azo dye used mainly in the coloring of waxes, oils, and plastics. It is a reddish-brown crystalline powder that is insoluble in water but soluble in most organic solvents. Sudan IV is commonly used as a dye to stain lipids, triglycerides, and lipoproteins in biological samples, especially in histology and cytology. However, it is also considered a carcinogen and mutagen, and its use is regulated in many countries due to its potential health hazards. Therefore, caution should be exercised when handling and using this chemical.Check Digit Verification of cas no
The CAS Registry Mumber 62637-98-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,2,6,3 and 7 respectively; the second part has 2 digits, 9 and 8 respectively.Calculate Digit Verification of CAS Registry Number 62637-98:
(7*6)+(6*2)+(5*6)+(4*3)+(3*7)+(2*9)+(1*8)=143
143 % 10 = 3
So 62637-98-3 is a valid CAS Registry Number.
