4-Nitro-trityl bromide, also known as 4-nitrophenyl triphenylmethyl bromide, is a chemical compound with the molecular formula C20H15BrNO2. It is a yellow crystalline solid that is soluble in organic solvents such as chloroform and dichloromethane. 4-nitro-trityl bromide is primarily used as a reagent in organic synthesis, particularly in the protection of alcohols and amines. The trityl group (triphenylmethyl) is a bulky, electron-rich protecting group that can be easily removed under mild acidic conditions, making it a valuable tool in the synthesis of complex organic molecules. 4-Nitro-trityl bromide is also known for its stability and selectivity, which are important factors in its application in chemical research and pharmaceutical development.

Check Digit Verification of cas no

The CAS Registry Mumber 3911-50-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,1 and 1 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 3911-50:
(6*3)+(5*9)+(4*1)+(3*1)+(2*5)+(1*0)=80
80 % 10 = 0
So 3911-50-0 is a valid CAS Registry Number.
