The chemical compound "O--D-α-hydroxy-isovaleriansaeure-tert.-butylester" is a complex organic molecule with a molecular formula of C26H36N2O8. It is a derivative of L-valine, an essential amino acid, and is characterized by the presence of a 4-nitro-benzyloxycarbonyl (Nboc) protecting group, a methyl group, and a tert-butyl ester group. O--D-α-hydroxy-isovaleriansaeure-tert.-butylester is often used in peptide synthesis as a protected amino acid building block, where the protecting groups can be selectively removed under specific conditions to facilitate the formation of peptide bonds. The α-hydroxy-isovaleric acid component adds to its structural complexity, making it a valuable intermediate in the synthesis of certain pharmaceuticals and bioactive peptides.

Check Digit Verification of cas no

The CAS Registry Mumber 4216-98-2 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 6 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4216-98:
(6*4)+(5*2)+(4*1)+(3*6)+(2*9)+(1*8)=82
82 % 10 = 2
So 4216-98-2 is a valid CAS Registry Number.
