"Z(OMe)-Gln-Ala-NHNH-Troc" is a peptide derivative with a specific chemical structure. It consists of a sequence of three amino acids: glutamine (Gln), alanine (Ala), and a terminal amino group (NHNH). The "Z(OMe)" prefix indicates the presence of a carbobenzoxy (Cbz) group, which is a protecting group used in peptide synthesis to prevent unwanted side reactions. The "Troc" suffix refers to the 2,2,2-trichloroethoxycarbonyl (Troc) group, another protecting group that shields the terminal amino group. Z(OMe)-Gln-Ala-NHNH-Troc is used in the synthesis of peptides and proteins, where the protecting groups are crucial for controlling the reaction conditions and ensuring the correct sequence of amino acids is formed. The Troc group can be selectively removed under mild conditions, allowing for the stepwise assembly of peptides.

Check Digit Verification of cas no

The CAS Registry Mumber 77694-03-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,6,9 and 4 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 77694-03:
(7*7)+(6*7)+(5*6)+(4*9)+(3*4)+(2*0)+(1*3)=172
172 % 10 = 2
So 77694-03-2 is a valid CAS Registry Number.
