General Description
2-Methoxy-4-[(4-nitrophenyl)diazenyl]aniline is a synthetic organic compound with the chemical formula C13H12N4O3. It falls under the category of azo dyes and is also known as Sudan I. This chemical is recognized for its bright red-orange color and has been used primarily as a dye in various industrial applications, such as coloring textiles and plastics. However, it's crucial to note that Sudan I, like many azo dyes, has faced regulatory restrictions due to potential health hazards. It has been associated with carcinogenicity and is banned or heavily regulated in several countries as a food additive due to its potential adverse effects on human health.Check Digit Verification of cas no
The CAS Registry Mumber 101-52-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,0 and 1 respectively; the second part has 2 digits, 5 and 2 respectively.Calculate Digit Verification of CAS Registry Number 101-52:
(5*1)+(4*0)+(3*1)+(2*5)+(1*2)=20
20 % 10 = 0
So 101-52-0 is a valid CAS Registry Number.
