α-tert-butyl N^α-(tert-butyloxycarbonyl)-N^δ-tosyl-N^δ-(benzyloxy)-L-ornithine is a complex organic compound with the molecular formula C₃₄H₅₂N₄O₆S. It is a derivative of L-ornithine, an amino acid, with several protecting groups attached to its nitrogen atoms. The α-tert-butyl group is a bulky protecting group that shields the α-amino group, while the N^α-(tert-butyloxycarbonyl) group is a commonly used protecting group for the α-amino group in peptide synthesis. The N^δ-tosyl group is a protecting group for the δ-amino group, and the N^δ-(benzyloxy) group is another protecting group for the δ-amino group. α-tert-butyl N^α-(tert-butyloxycarbonyl)-N^δ-tosyl-N^δ-(benzyloxy)-L-ornithine is used in the synthesis of peptides and other organic compounds, where the protecting groups can be selectively removed to reveal the free amino acid.

Check Digit Verification of cas no

The CAS Registry Mumber 91229-90-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,2,2 and 9 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 91229-90:
(7*9)+(6*1)+(5*2)+(4*2)+(3*9)+(2*9)+(1*0)=132
132 % 10 = 2
So 91229-90-2 is a valid CAS Registry Number.
