N-pivaloylphthalimide (NPI) is a chemical compound with the molecular formula C12H15NO3. It is a derivative of phthalimide, where the hydrogen atom on the nitrogen atom is replaced by a pivaloyl group (a tert-butyl ester of acetic acid). NPI is a white crystalline solid that is soluble in most organic solvents. It is commonly used as a protecting group in organic synthesis, particularly for amines, due to its stability and ease of removal under mild acidic conditions. The compound is also known for its use in the synthesis of various pharmaceuticals and agrochemicals, as well as in the preparation of other specialty chemicals. NPI is a valuable reagent in the field of organic chemistry, providing a convenient way to protect and deprotect amines in complex molecular structures.

Check Digit Verification of cas no

The CAS Registry Mumber 4658-63-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,5 and 8 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4658-63:
(6*4)+(5*6)+(4*5)+(3*8)+(2*6)+(1*3)=113
113 % 10 = 3
So 4658-63-3 is a valid CAS Registry Number.
