Val-Thr(OBzl)-OBzl is a peptide fragment consisting of two amino acids, valine (Val) and threonine (Thr), with a benzyl (OBzl) protecting group on the hydroxyl group of threonine. This chemical structure is commonly used in peptide synthesis, where protecting groups are essential to prevent unwanted side reactions during the assembly of peptide chains. The benzyl group is a temporary modification that can be removed under specific conditions once the peptide synthesis is complete, allowing for the formation of the desired peptide bond between the amino acids. The presence of the OBzl group on threonine in Val-Thr(OBzl)-OBzl ensures that the hydroxyl group remains unreactive until the appropriate time in the synthesis process.

Check Digit Verification of cas no

The CAS Registry Mumber 99429-42-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,4,2 and 9 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 99429-42:
(7*9)+(6*9)+(5*4)+(4*2)+(3*9)+(2*4)+(1*2)=182
182 % 10 = 2
So 99429-42-2 is a valid CAS Registry Number.
