Z-Cys(SiPr)-OH*DCHA is a complex chemical compound, where "Z" stands for the benzyloxycarbonyl protecting group, "Cys" represents cysteine, an amino acid with a thiol side chain, "SiPr" denotes the silyl protecting group, and "OH" indicates the presence of a hydroxyl group. "DCHA" refers to dicyclohexylamine, which is often used as a base in organic synthesis. Z-Cys(SiPr)-OH*DCHA is primarily used in peptide synthesis, where the protecting groups help to prevent unwanted side reactions and ensure the correct sequence of amino acids in the final peptide product. The combination of these elements in Z-Cys(SiPr)-OH*DCHA makes it a valuable tool in the field of biochemistry and pharmaceutical research, particularly for the synthesis of peptides and proteins with specific functional groups.
The CAS Registry Mumber 76969-43-2 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 3 respectively. Calculate Digit Verification of CAS Registry Number 76969-43: (7*7)+(6*6)+(5*9)+(4*6)+(3*9)+(2*4)+(1*3)=192 192 % 10 = 2 So 76969-43-2 is a valid CAS Registry Number.
