α-Phenyl-propionsaeuretosylamid, also known as N-tosyl-α-phenylpropionamide, is an organic compound with the chemical formula C11H13NO3S. It is a derivative of α-phenylpropionic acid, where the carboxylic acid group is replaced by a tosylamide group. α-Phenyl-propionsaeuretosylamid is a white crystalline solid and is used as a reagent in organic synthesis, particularly in the preparation of various pharmaceuticals and other chemical compounds. It is also employed as a protecting group in peptide synthesis due to its stability and ease of removal under mild conditions. The compound is synthesized by reacting α-phenylpropionic acid with tosyl chloride in the presence of a base, such as pyridine.

Check Digit Verification of cas no

The CAS Registry Mumber 3897-87-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,9 and 7 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 3897-87:
(6*3)+(5*8)+(4*9)+(3*7)+(2*8)+(1*7)=138
138 % 10 = 8
So 3897-87-8 is a valid CAS Registry Number.
