1166833-32-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1166833-32-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,6,6,8,3 and 3 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1166833-32:
(9*1)+(8*1)+(7*6)+(6*6)+(5*8)+(4*3)+(3*3)+(2*3)+(1*2)=164
164 % 10 = 4
So 1166833-32-4 is a valid CAS Registry Number.

Internal cysteine accelerates thioester-based peptide ligation
Haase, Christian,Seitz, Oliver
supporting information; experimental part, p. 2096 - 2101 (2009/10/04)
Thioester-mediated peptide coupling reactions are powerful tools in protein synthesis. The fragment coupling occurs extremely fast at ligation sites that contain an N-terminal cyste- ine residue. This native chemical ligation involves a capture step that
