4-Mesyl-2-nitroaniline is a chemical compound characterized by a benzene ring substituted with a mesyl group (SO3CH3), an amino group (NH2), and a nitro group (NO2). It is a versatile intermediate in various chemical reactions due to its distinct chemical properties. The mesyl group serves as a good leaving group in nucleophilic substitution reactions, while the nitro group's electron-withdrawing nature reduces the benzene ring's reactivity towards electrophilic aromatic substitution. The amino group can participate in reactions such as diazotization or amide formation. 4-mesyl-2-nitroaniline is typically found as an off-white to beige solid and requires careful handling due to its potential toxicity and reactivity.

Check Digit Verification of cas no

The CAS Registry Mumber 21731-56-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,7,3 and 1 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 21731-56:
(7*2)+(6*1)+(5*7)+(4*3)+(3*1)+(2*5)+(1*6)=86
86 % 10 = 6
So 21731-56-6 is a valid CAS Registry Number.
