"O-(2-Benzyloxycarbonyl-benzoyl)-α-hydroxy-isovaleriansaeure-tert.-butylester" is a complex organic compound with the molecular formula C22H27NO6. It is a derivative of isovaleric acid, featuring a tert-butyl ester group and a benzyloxycarbonyl-benzoyl moiety. O-(2-Benzyloxycarbonyl-benzoyl)-α-hydroxy-isovaleriansaeure-tert.-butylester is often used in peptide synthesis as a protecting group for the α-hydroxy acid functionality, which helps prevent unwanted side reactions during the assembly of peptide chains. The benzyloxycarbonyl (Z) group is a common protecting group that can be selectively removed under mild acidic conditions, making it a valuable tool in the synthesis of complex peptides and proteins.

Check Digit Verification of cas no

The CAS Registry Mumber 2634-27-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,3 and 4 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2634-27:
(6*2)+(5*6)+(4*3)+(3*4)+(2*2)+(1*7)=77
77 % 10 = 7
So 2634-27-7 is a valid CAS Registry Number.
