Triphenylmethyl-m-nitro-phenylsulfon, also known as trityl methanesulfonate, is a chemical compound with the molecular formula C21H17NO4S. It is a derivative of triphenylmethyl, where one of the phenyl groups is replaced by a m-nitrophenylsulfonate group. Triphenylmethyl-m-nitro-phenylsulfon is often used as a protecting group in organic synthesis, particularly for alcohols and amines, due to its stability and ease of removal under mild acidic conditions. The trityl group can be introduced to a molecule to prevent unwanted side reactions and then removed when necessary, making it a valuable tool in the synthesis of complex organic molecules.

Check Digit Verification of cas no

The CAS Registry Mumber 24760-13-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,7,6 and 0 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 24760-13:
(7*2)+(6*4)+(5*7)+(4*6)+(3*0)+(2*1)+(1*3)=102
102 % 10 = 2
So 24760-13-2 is a valid CAS Registry Number.
