2-((R)-2-Benzyloxycarbonylamino-propionylamino)-propionic acid ethyl ester is a complex organic compound with the molecular formula C16H23NO5. It is a derivative of propionic acid, featuring an ethyl ester group and a benzyloxycarbonyl (Cbz) protecting group. 2-((R)-2-Benzyloxycarbonylamino-propionylamino)-propionic acid ethyl ester is characterized by the presence of an amino group attached to a propionylamino chain, which is further connected to a propionic acid backbone. The R-configuration at the second carbon indicates the specific stereochemistry of the molecule. It is often used in peptide synthesis as a building block or as a protected amino acid, where the Cbz group can be removed under certain conditions to reveal the free amine group, facilitating further reactions in the synthesis of peptides and proteins.

Check Digit Verification of cas no

The CAS Registry Mumber 57355-16-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,3,5 and 5 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 57355-16:
(7*5)+(6*7)+(5*3)+(4*5)+(3*5)+(2*1)+(1*6)=135
135 % 10 = 5
So 57355-16-5 is a valid CAS Registry Number.
