65057-34-3 Usage
General Description
BOC-HIS(TOS)-OH DCHA is a chemical compound consisting of a BOC-protected histidine (BOC-HIS) with a tosyl (TOS) functional group attached to the nitrogen atom. The DCHA attached to the carboxylic acid group also serves as a protecting group. BOC-HIS(TOS)-OH DCHA is commonly used as a building block in peptide synthesis, where the BOC protecting group can be removed under mild acidic conditions to reveal the free amine group for peptide coupling reactions. The tosyl group can also serve as a protecting group for the histidine side chain, providing additional selectivity in peptide synthesis. Overall, BOC-HIS(TOS)-OH DCHA is a versatile tool for the construction of complex peptides in organic chemistry.
Check Digit Verification of cas no
The CAS Registry Mumber 65057-34-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,0,5 and 7 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 65057-34:
(7*6)+(6*5)+(5*0)+(4*5)+(3*7)+(2*3)+(1*4)=123
123 % 10 = 3
So 65057-34-3 is a valid CAS Registry Number.
