4663-94-9 Usage
General Description
PYRIDINE-2,3-DICARBOXAMIDE, also known as nicotinamide, is a chemical compound with the molecular formula C6H6N2O. It is the amide form of nicotinic acid, also known as niacin or vitamin B3, and is an essential nutrient for the human body. Nicotinamide plays a crucial role in the metabolism of fats, proteins, and carbohydrates, and is important for the synthesis of DNA and cell repair. It is also known for its anti-inflammatory and antioxidant properties, and is often used in various skincare and cosmetic products for its ability to improve the appearance of aging skin and reduce the risk of certain skin cancers. Additionally, nicotinamide has been studied for its potential role in the prevention and treatment of certain medical conditions, such as diabetes, Alzheimer's disease, and sunburn.
Check Digit Verification of cas no
The CAS Registry Mumber 4663-94-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,6 and 3 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4663-94:
(6*4)+(5*6)+(4*6)+(3*3)+(2*9)+(1*4)=109
109 % 10 = 9
So 4663-94-9 is a valid CAS Registry Number.
