Phenyl-β-naphthylessigsaeure-tosylamid, also known as phenyl-β-naphthoyltosylamide, is a complex organic chemical compound with the molecular formula C23H17NO3S. It is derived from the condensation of phenyl-β-naphthoyl chloride with tosylamide, resulting in a white crystalline solid. Phenyl-β-naphthylessigsaeure-tosylamid is primarily used as a reagent in organic synthesis, particularly in the preparation of various heterocyclic compounds and as a protecting group in peptide synthesis. Its chemical structure features a phenyl group, a β-naphthyl group, and a tosylamide group, which contribute to its unique reactivity and utility in chemical transformations.
The CAS Registry Mumber 3864-26-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,6 and 4 respectively; the second part has 2 digits, 2 and 6 respectively. Calculate Digit Verification of CAS Registry Number 3864-26: (6*3)+(5*8)+(4*6)+(3*4)+(2*2)+(1*6)=104 104 % 10 = 4 So 3864-26-4 is a valid CAS Registry Number.
