2-ethyl-6-tert-butyl-3-methyl-phenol, also known as BHT or butylated hydroxytoluene, is a widely used synthetic antioxidant and preservative. It is an organic compound with a molecular formula of C15H24O. BHT is a white crystalline solid that is soluble in organic solvents but poorly soluble in water. It is commonly used in the food industry to prevent oxidation and spoilage, as well as in the rubber, petroleum, and chemical industries to protect materials from degradation. BHT is effective in stabilizing fats and oils, preventing rancidity, and extending the shelf life of products. However, its use has been a subject of debate due to potential health concerns, and it is regulated in various countries to ensure safety.
The CAS Registry Mumber 2570-93-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,7 and 0 respectively; the second part has 2 digits, 9 and 3 respectively. Calculate Digit Verification of CAS Registry Number 2570-93: (6*2)+(5*5)+(4*7)+(3*0)+(2*9)+(1*3)=86 86 % 10 = 6 So 2570-93-6 is a valid CAS Registry Number.
