Trityl-β-cyano-DL-alanin, also known as 2-cyano-N-(9H-fluoren-9-ylmethoxycarbonyl)-DL-alanine, is a synthetic chemical compound with the molecular formula C22H20N2O3. It is a derivative of the amino acid alanine, featuring a trityl group (9H-fluoren-9-ylmethoxycarbonyl) attached to the nitrogen atom and a cyano group (-CN) at the β-position. Trityl-β-cyano-DL-alanin is often used as a protecting group in peptide synthesis, particularly in solid-phase peptide synthesis, to protect the α-amino group of alanine from unwanted side reactions. The trityl group can be removed under mild acidic conditions, allowing for the subsequent coupling of other amino acids to form peptides.

Check Digit Verification of cas no
The CAS Registry Mumber 10513-13-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,5,1 and 3 respectively; the second part has 2 digits, 1 and 3 respectively.Calculate Digit Verification of CAS Registry Number 10513-13:
(7*1)+(6*0)+(5*5)+(4*1)+(3*3)+(2*1)+(1*3)=50
50 % 10 = 0
So 10513-13-0 is a valid CAS Registry Number.
