Val-Asp(OBzl)-OBzl is a peptide derivative consisting of two amino acids, valine (Val) and aspartic acid (Asp), with a benzyl (OBzl) protecting group on the side chain of aspartic acid. This chemical structure is significant in peptide chemistry as it represents a building block for the synthesis of larger peptides and proteins. The benzyl protecting group is crucial for preventing unwanted side reactions during peptide synthesis, particularly protecting the carboxylic acid group of aspartic acid from unwanted reactions until the desired peptide bond formation is complete. Once the peptide is fully synthesized, the protecting group can be removed to reveal the free carboxylic acid group, allowing for further reactions or the formation of the final peptide product. Val-Asp(OBzl)-OBzl is an example of the精细化学 techniques used in the preparation of complex biologically active molecules.

Check Digit Verification of cas no

The CAS Registry Mumber 70853-20-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,8,5 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 70853-20:
(7*7)+(6*0)+(5*8)+(4*5)+(3*3)+(2*2)+(1*0)=122
122 % 10 = 2
So 70853-20-2 is a valid CAS Registry Number.
