189359-24-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 189359-24-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,3,5 and 9 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 189359-24:
(8*1)+(7*8)+(6*9)+(5*3)+(4*5)+(3*9)+(2*2)+(1*4)=188
188 % 10 = 8
So 189359-24-8 is a valid CAS Registry Number.

Total synthesis of luzopeptin E2
Ciufolini, Marco A.,Valognes, Delphine,Xi, Ning
, p. 2493 - 2495 (2007/10/03)
The self-assembly of the 32-membered macrocycle of iuzopeptin E2 (1) has been accomplished by cyclodimerization of a terminally unprotected pentapeptide monomer. This is the key step of the first total synthesis of this macrocyclic antitumor decadepsipept
