"Z-L-Phe-O-N=C(CH3)-C6H4-m-NO2" is a complex chemical compound, which can be broken down into its constituent parts for better understanding. The "Z" prefix indicates that the compound is in the Z configuration, referring to the geometric arrangement of the molecule. "L-Phe" stands for L-phenylalanine, an essential amino acid that is a building block of proteins. The "O-N=C" part suggests the presence of an amide bond, which is a peptide bond in this context, connecting the phenylalanine to the rest of the molecule. "(CH3)" represents a methyl group, a single carbon atom bonded to three hydrogen atoms. "C6H4" is a benzene ring with four carbon atoms, and the "m-NO2" indicates a nitro group (NO2) attached to the meta position of the benzene ring, which is the middle carbon when considering the ring's structure. Overall, Z-L-Phe-O-N=C(CH3)-C6H4-m-NO2 is a derivative of phenylalanine with a specific chemical modification that includes a nitro group on a benzene ring attached via an amide bond.

Check Digit Verification of cas no

The CAS Registry Mumber 2688-13-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,8 and 8 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 2688-13:
(6*2)+(5*6)+(4*8)+(3*8)+(2*1)+(1*3)=103
103 % 10 = 3
So 2688-13-3 is a valid CAS Registry Number.
