α-(4-Nitro-benzoyloxy)-methyl-methylsulfon, also known as α-(4-nitrobenzoyloxy)methyl methanesulfonate, is a chemical compound with the molecular formula C10H11NO6S. It is a derivative of methanesulfonate, featuring a nitrobenzoyloxy group attached to the alpha carbon. α-<4-Nitro-benzoyloxy>-methyl-methylsulfon is often used as a protecting group in organic synthesis, particularly in the protection of alcohols and amines. The nitrobenzoyloxy group can be selectively removed under mild acidic conditions, making it a valuable tool in the synthesis of complex molecules where temporary protection of functional groups is required. Its stability and reactivity make it a popular choice in various chemical transformations, including the preparation of pharmaceuticals and other specialty chemicals.

Check Digit Verification of cas no

The CAS Registry Mumber 5388-05-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,8 and 8 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 5388-05:
(6*5)+(5*3)+(4*8)+(3*8)+(2*0)+(1*5)=106
106 % 10 = 6
So 5388-05-6 is a valid CAS Registry Number.
