(S)-2,4-bis-benzyloxycarbonylamino-butyric acid amide is a complex organic compound with the molecular formula C22H26N2O6. It is a chiral molecule, meaning it has a non-superimposable mirror image, and the "S" prefix indicates that it is the (S)-enantiomer. (S)-2,4-bis-benzyloxycarbonylamino-butyric acid amide is characterized by its two benzyloxycarbonyl (Cbz) protecting groups, which are commonly used in peptide synthesis to protect the amino group. The compound features a central butyric acid backbone with an amide group at the end, which can participate in various chemical reactions. It is used in the synthesis of peptides and other biologically active molecules, where the Cbz groups can be removed under specific conditions to reveal the free amino groups, allowing for further reactions or the formation of peptide bonds.
The CAS Registry Mumber 4218-64-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,1 and 8 respectively; the second part has 2 digits, 6 and 4 respectively. Calculate Digit Verification of CAS Registry Number 4218-64: (6*4)+(5*2)+(4*1)+(3*8)+(2*6)+(1*4)=78 78 % 10 = 8 So 4218-64-8 is a valid CAS Registry Number.
