Tert-Butyloxycarbonylmethionin-<4-nitrophenylester>-dl-sulfoxid is a complex organic compound with the chemical formula C18H24N2O8S. It is a derivative of methionine, an essential amino acid, with a tert-butyloxycarbonyl (Boc) protecting group, a 4-nitrophenyl ester group, and a sulfoxide functional group. tert-Butyloxycarbonylmethionin-<4-nitrophenylester>-dl-sulfoxid is often used in peptide synthesis as a protected form of methionine, allowing for the incorporation of the amino acid into peptide sequences while preventing unwanted side reactions. The Boc group can be removed under acidic conditions, while the 4-nitrophenyl ester group can be hydrolyzed under basic conditions, releasing the free methionine sulfoxide. tert-Butyloxycarbonylmethionin-<4-nitrophenylester>-dl-sulfoxid is valuable in the field of biochemistry and pharmaceuticals for the synthesis of peptides and proteins with specific properties.

Check Digit Verification of cas no

The CAS Registry Mumber 2488-20-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,4,8 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 2488-20:
(6*2)+(5*4)+(4*8)+(3*8)+(2*2)+(1*0)=92
92 % 10 = 2
So 2488-20-2 is a valid CAS Registry Number.
