66085-70-9 Usage

General Description

1-[[4-[[4-[(2-hydroxy-1-naphthyl)azo]-2,5-dimethylphenyl]phenylmethyl]-2-methylphenyl]azo]-2-naphthol, also known as Sudan I, is a synthetic azo dye that is commonly used to color industrial products such as oils, waxes, and polishes. However, it is also known to be a potential carcinogen, and its use in food products is prohibited in many countries. Ingestion of Sudan I has been linked to liver and bladder cancer, and it has been the focus of food safety regulations and recalls due to its potential health risks. Due to its carcinogenic properties, the use of Sudan I has become heavily restricted and regulated, with efforts to find alternative colorants for industrial and consumer products.

Check Digit Verification of cas no

The CAS Registry Mumber 66085-70-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,0,8 and 5 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 66085-70:
(7*6)+(6*6)+(5*0)+(4*8)+(3*5)+(2*7)+(1*0)=139
139 % 10 = 9
So 66085-70-9 is a valid CAS Registry Number.
