"Z-L-Phe-Gly-Gly-Tyr(O-t-Bu)-O-t-Bu" is a peptide compound consisting of five amino acids: L-phenylalanine (L-Phe), glycine (Gly), and tyrosine (Tyr) with a tert-butyl (t-Bu) protecting group on the hydroxyl group. The "Z" prefix indicates the presence of a benzyloxycarbonyl (Cbz) protecting group on the N-terminus, which is commonly used in peptide synthesis to prevent unwanted side reactions. This specific sequence and structure are relevant in the field of organic chemistry and peptide synthesis, where protecting groups are crucial for controlling the reactivity of functional groups during the assembly of complex molecules.

Check Digit Verification of cas no

The CAS Registry Mumber 77659-03-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,6,5 and 9 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 77659-03:
(7*7)+(6*7)+(5*6)+(4*5)+(3*9)+(2*0)+(1*3)=171
171 % 10 = 1
So 77659-03-1 is a valid CAS Registry Number.
