β-Methyl-β-(2-hydroxy-3,5-dinitrophenyl)propionic acid, also known as DNP, is a chemical compound with the formula C9H7N3O6. It is a yellow crystalline solid that is soluble in water and ethanol. DNP was historically used as a weight loss drug due to its ability to increase metabolism by uncoupling oxidative phosphorylation in mitochondria, leading to increased heat production and energy expenditure. However, its use has been discontinued in most countries due to severe side effects, including cataracts, hyperthermia, and even death. The compound is also used as a chemical intermediate in the synthesis of other compounds and as a reagent in analytical chemistry.

Check Digit Verification of cas no

The CAS Registry Mumber 28443-64-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,4,4 and 3 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 28443-64:
(7*2)+(6*8)+(5*4)+(4*4)+(3*3)+(2*6)+(1*4)=123
123 % 10 = 3
So 28443-64-3 is a valid CAS Registry Number.
