"Z(OMe)-Asn-ONb" refers to a chemical compound that is a protected form of asparagine (Asn), an amino acid. The "Z" group is a benzyloxycarbonyl (Cbz) protecting group, which is commonly used in peptide synthesis to prevent unwanted side reactions. The "OMe" indicates that the hydroxyl group of the asparagine side chain is methylated, which can help stabilize the molecule and prevent unwanted reactions. The "ONb" part signifies that the nitrogen atom of the asparagine side chain is protected with a 2-nitrobenzyl group, which is another protecting group used in peptide chemistry. Z(OMe)-Asn-ONb is used in the synthesis of peptides where the asparagine residue needs to be protected to prevent unwanted side reactions during the assembly process. The protection is crucial for maintaining the integrity of the peptide sequence and ensuring that the final product has the desired biological activity.

Check Digit Verification of cas no

The CAS Registry Mumber 83550-74-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,5,5 and 0 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 83550-74:
(7*8)+(6*3)+(5*5)+(4*5)+(3*0)+(2*7)+(1*4)=137
137 % 10 = 7
So 83550-74-7 is a valid CAS Registry Number.
