5-tert-butoxycarbonyl-2-oxa-5-azabicyclo[2.2.1]heptane-1-carboxylic acid is a complex organic compound with the molecular formula C12H19NO5. It is a derivative of 2-oxa-5-azabicyclo[2.2.1]heptane, featuring a carboxylic acid group at the 1-position, a 5-membered ring with an oxygen atom, and a 5-membered ring with a nitrogen atom. The tert-butoxycarbonyl group is attached to the 5-position, providing protection for the nitrogen atom. 5-tert-butoxycarbonyl-2-oxa-5-azabicyclo[2.2.1]heptane-1-carboxylic acid is often used as a protecting group in peptide synthesis, as it can be selectively removed under mild acidic conditions, allowing for the controlled formation of peptide bonds. Its stability and reactivity make it a valuable tool in the synthesis of complex peptide structures.

1330763-18-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1330763-18-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,0,7,6 and 3 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1330763-18:
(9*1)+(8*3)+(7*3)+(6*0)+(5*7)+(4*6)+(3*3)+(2*1)+(1*8)=132
132 % 10 = 2
So 1330763-18-2 is a valid CAS Registry Number.
