7474-93-3 Usage
General Description
4-(acetylamino)-3-aminophenyl acetate, also known as paracetamol or acetaminophen, is a chemical compound commonly used as a pain reliever and fever reducer. It is a white, crystalline powder that is typically administered orally. Paracetamol is considered a nonsteroidal anti-inflammatory drug (NSAID) and works by inhibiting the production of prostaglandins in the brain, which are responsible for transmitting pain signals. It is commonly utilized to treat a variety of conditions, including headaches, muscle aches, arthritis, and fevers. Paracetamol is generally considered safe when taken in recommended doses, but can cause liver damage if taken in excess.
Check Digit Verification of cas no
The CAS Registry Mumber 7474-93-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,4,7 and 4 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 7474-93:
(6*7)+(5*4)+(4*7)+(3*4)+(2*9)+(1*3)=123
123 % 10 = 3
So 7474-93-3 is a valid CAS Registry Number.

Acylamino-Directed Specific Sequential Difunctionalizations of Anilides via Metal-Free Relay Reactions for p-Oxygen and o-Nitrogen Incorporation
Wan, Yameng,Zhang, Zhiguo,Ma, Nana,Bi, Jingjing,Zhang, Guisheng
, p. 780 - 791 (2019/01/24)
Novel acylamino-directed relay disubstitutions realize the sequential difunctionalizations of anilides (1) under mild and metal-free conditions for the first time. This [bis(trifluoroacetoxy)iodo]benzene (PIFA) and BF3·Et2O promoted straightforward reaction produces a series of p-acetoxyl- or p-alkoxyl-o-nitro-N-arylamides (2), which are key scaffolds of various drugs, functional materials, and bioactive molecules. The flexibility with respect to the functional groups in these products affords this novel protocol excellent versatility for synthetic applications.
