7-Hydroxy-3-(4-methoxyphenyl)-4-propyl-2H-chromen-2-one, also known as naringin, is a flavonoid compound found in citrus fruits, particularly grapefruits. It is a chalcone derivative, characterized by its yellow color and bitter taste. Naringin exhibits various biological activities, such as antioxidant, anti-inflammatory, and anticancer properties. It is also known for its potential role in weight loss and cholesterol reduction. However, its bioavailability is limited due to its poor absorption in the gastrointestinal tract and rapid metabolism. Research is ongoing to explore the potential health benefits and applications of naringin in pharmaceutical and nutraceutical industries.

Check Digit Verification of cas no

The CAS Registry Mumber 5219-18-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,1 and 9 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 5219-18:
(6*5)+(5*2)+(4*1)+(3*9)+(2*1)+(1*8)=81
81 % 10 = 1
So 5219-18-1 is a valid CAS Registry Number.
