β-(N-Tosyl-β-alanylamino)-propionitril is a complex organic compound with the chemical formula C12H14N2O2S. It is a derivative of β-alanine, an amino acid, and features a tosyl group (tosyl = 4-methylbenzenesulfonyl) attached to the nitrogen atom. β-(N-Tosyl-β-alanylamino)-propionitril is known for its use in peptide synthesis, particularly in the formation of β-peptides, which are a type of non-natural peptide that can have unique properties compared to traditional α-peptides. The presence of the tosyl group provides a protecting group for the amine function, which is crucial for controlling the reactivity and selectivity in peptide bond formation. The compound's structure allows for the controlled deprotection and coupling reactions necessary for the synthesis of complex peptide sequences.

Check Digit Verification of cas no

The CAS Registry Mumber 19822-87-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,8,2 and 2 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 19822-87:
(7*1)+(6*9)+(5*8)+(4*2)+(3*2)+(2*8)+(1*7)=138
138 % 10 = 8
So 19822-87-8 is a valid CAS Registry Number.
