Bernsteinsaeure-phenylester-benzyloxyamid, also known as benzyloxycarbonyl phenylacetate, is a chemical compound with the molecular formula C16H15O4. It is a derivative of phenylacetic acid, where the hydroxyl group is replaced by a benzyloxycarbonyl group. Bernsteinsaeure-phenylester-benzyloxyamid is often used in organic synthesis and pharmaceutical chemistry as a protecting group for amines and alcohols. The benzyloxycarbonyl (Z) group is a popular choice for protection due to its stability and ease of removal under mild acidic conditions. It plays a crucial role in the synthesis of various pharmaceuticals and biologically active compounds, where selective protection and deprotection of functional groups are essential for the successful assembly of complex molecules.

Check Digit Verification of cas no

The CAS Registry Mumber 740-81-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,4 and 0 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 740-81:
(5*7)+(4*4)+(3*0)+(2*8)+(1*1)=68
68 % 10 = 8
So 740-81-8 is a valid CAS Registry Number.
