N-phthaloyl-asparagine is a chemical compound derived from the amino acid asparagine, where the amino group is acylated with phthalic anhydride. This modification results in a more stable and less reactive form of asparagine, which can be useful in various chemical and biological applications. The compound is often used in peptide synthesis, where it can be incorporated into peptide sequences and later deprotected to regenerate the free amino acid. N-phthaloyl-asparagine is also employed in the study of protein structure and function, as it can help to stabilize certain protein conformations and facilitate the analysis of protein-protein interactions. Overall, this chemical serves as a valuable tool in the fields of organic chemistry, biochemistry, and molecular biology.
The CAS Registry Mumber 303-24-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,0 and 3 respectively; the second part has 2 digits, 2 and 4 respectively. Calculate Digit Verification of CAS Registry Number 303-24: (5*3)+(4*0)+(3*3)+(2*2)+(1*4)=32 32 % 10 = 2 So 303-24-2 is a valid CAS Registry Number.
