Z-Cys(SBut)-OH*DCHA is a chemical compound that consists of a protected cysteine residue, where the thiol group is blocked by a tert-butyl (t-Bu) group, and the carboxylic acid group is activated with dicyclohexylcarbodiimide (DCHA). Z-Cys(SBut)-OH*DCHA is commonly used in peptide synthesis to introduce a cysteine residue into a peptide sequence while preventing unwanted side reactions, such as disulfide bond formation. The Z group (benzyloxycarbonyl) is a protecting group for the amino group, which is crucial for maintaining the stability of the peptide during synthesis. The DCHA activation enhances the reactivity of the carboxylic acid, facilitating its coupling with other amino acids in the peptide chain. Overall, Z-Cys(SBut)-OH*DCHA is a key component in the synthesis of peptides containing cysteine, ensuring the controlled formation of the desired peptide structure.

Check Digit Verification of cas no

The CAS Registry Mumber 76969-41-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,9,6 and 9 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 76969-41:
(7*7)+(6*6)+(5*9)+(4*6)+(3*9)+(2*4)+(1*1)=190
190 % 10 = 0
So 76969-41-0 is a valid CAS Registry Number.
