Z-Asn-Cys(CH2SBzl)-OMe is a synthetic peptide derivative, where "Z" stands for the benzyloxycarbonyl (Cbz) protecting group, "Asn" represents asparagine, "Cys" stands for cysteine, "CH2SBzl" indicates a benzyl-protected thiol group, and "OMe" denotes a methoxy group. Z-Asn-Cys(CH₂SBzl)-OMe is often used in peptide synthesis to protect the side chain functionalities of asparagine and cysteine, which are sensitive to chemical reactions during peptide bond formation. The benzyl group in "CH2SBzl" protects the thiol group of cysteine, preventing unwanted side reactions, while the methoxy group in "OMe" is a simple protecting group for the hydroxyl group of the peptide backbone. The Z group is used to protect the amino group of asparagine, which is crucial for maintaining the peptide's stability and preventing premature reactions. This protected peptide can be used in the synthesis of larger peptides or proteins, where the protecting groups are later removed under specific conditions to reveal the native peptide sequence.

Check Digit Verification of cas no

The CAS Registry Mumber 4801-55-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,0 and 1 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4801-55:
(6*4)+(5*8)+(4*0)+(3*1)+(2*5)+(1*5)=82
82 % 10 = 2
So 4801-55-2 is a valid CAS Registry Number.
