201811-20-3 Usage
General Description
Tert-butyl 4-hydroxy-2-nitrophenylcarbaMate, also known as butylated hydroxyanisole (BHA), is a synthetic antioxidant commonly used in food, cosmetics, and pharmaceuticals to prevent spoilage and oxidation. It is a white or yellowish waxy solid with a faint characteristic odor and is soluble in methanol and ethanol. BHA works by inhibiting the oxidation of fats and oils, thus extending the shelf life of products. While it is generally recognized as safe for consumption in small amounts, there has been some controversy and concern about its potential health effects, particularly its possible carcinogenic properties. As a result, its usage in food products is regulated in some countries, and alternative natural antioxidants are being explored.
Check Digit Verification of cas no
The CAS Registry Mumber 201811-20-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,1,8,1 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 201811-20:
(8*2)+(7*0)+(6*1)+(5*8)+(4*1)+(3*1)+(2*2)+(1*0)=73
73 % 10 = 3
So 201811-20-3 is a valid CAS Registry Number.

FGFR INHIBITORS FOR THE TREATMENT OF CANCER
-
Paragraph 00173; 00174, (2020/08/28)
The disclosure provides novel FGFR inhibitors based on the pyridinylpyrimidine. The disclosure includes inhibitors with broad inhibitory activity against all FGFR isoforms, and inhibitors with selective inhibition against FGFR4. These novel pyridinylpyrimidine-based FGFR inhibitors, or their derivatives, have strong potential to be used to treat cancer.
