"Z(OMe)-Asp(OBzl)-Val-Gln-Ala-NHNH-Troc" represents a peptide sequence with specific chemical modifications. The peptide consists of six amino acids: Z(OMe), Asp(OBzl), Val, Gln, Ala, and NHNH, with a Troc group at the end. Z(OMe) refers to a carbobenzoxy group (Cbz) with a methoxy group (OMe) attached to the N-terminus, protecting the amino group. Asp(OBzl) denotes an aspartic acid residue with a benzyl ester (OBzl) protecting the carboxylic acid group. Val is valine, Gln is glutamine, Ala is alanine, and NHNH represents a terminal amino group. The Troc group, or 2,2,2-trichloroethoxycarbonyl, is a temporary protecting group for the terminal amino group, which can be removed under specific conditions to reveal the free amine. This sequence is likely used in peptide synthesis, where the protecting groups are strategically placed to prevent unwanted side reactions and are removed at appropriate stages to allow for further reactions or to activate the peptide for biological studies.

Check Digit Verification of cas no

The CAS Registry Mumber 76224-17-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,2,2 and 4 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 76224-17:
(7*7)+(6*6)+(5*2)+(4*2)+(3*4)+(2*1)+(1*7)=124
124 % 10 = 4
So 76224-17-4 is a valid CAS Registry Number.
