p-Nitrophenyl N-methoxycarbonyl-D-phenylalaninate is a complex organic compound with the chemical formula C18H16N2O6. It is a derivative of phenylalanine, an essential amino acid, where the nitrogen atom is protected by a methoxycarbonyl (MOC) group and the phenyl ring is substituted with a nitro group at the para position. p-nitrophenyl N-methoxycarbonyl-D-phenylalaninate is often used in peptide synthesis as a protected amino acid building block, allowing for the controlled formation of peptide bonds in the presence of other functional groups. The nitro group provides a chromophore, enabling the compound to absorb light in the visible spectrum, which can be useful for monitoring reactions or as a reporter group in various biochemical assays. Its unique structure also makes it a valuable intermediate in the synthesis of pharmaceuticals and other bioactive molecules.

Check Digit Verification of cas no

The CAS Registry Mumber 1223-26-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,2 and 3 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1223-26:
(6*1)+(5*2)+(4*2)+(3*3)+(2*2)+(1*6)=43
43 % 10 = 3
So 1223-26-3 is a valid CAS Registry Number.
