Meso-2,6-bis-(tert-butyloxycarbonylamino)-pimelic acid is a complex organic compound with the molecular formula C18H32N2O8. It is a derivative of pimelic acid, a dicarboxylic acid with six carbon atoms, where both carboxylic acid groups are replaced by tert-butyloxycarbonyl (Boc) protected amino groups. meso-2,6-Bis--pimelinsaeure is often used as a building block in peptide synthesis, particularly in the preparation of cyclic peptides, due to its symmetrical structure and the protection of the amino groups by the Boc group, which prevents unwanted side reactions during peptide bond formation. The Boc protecting group can be removed under acidic conditions when needed, allowing for further reactions or peptide elongation.
The CAS Registry Mumber 4243-01-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,4 and 3 respectively; the second part has 2 digits, 0 and 1 respectively. Calculate Digit Verification of CAS Registry Number 4243-01: (6*4)+(5*2)+(4*4)+(3*3)+(2*0)+(1*1)=60 60 % 10 = 0 So 4243-01-0 is a valid CAS Registry Number.
