547739-20-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 547739-20-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,4,7,7,3 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 547739-20:
(8*5)+(7*4)+(6*7)+(5*7)+(4*3)+(3*9)+(2*2)+(1*0)=188
188 % 10 = 8
So 547739-20-8 is a valid CAS Registry Number.

Total synthesis of the salicylate enamide macrolide oximidine II
Wang, Xiang,Porco Jr., John A.
, p. 6040 - 6041 (2007/10/03)
The asymmetric synthesis of the salicylate enamide macrolide oximidine II is reported. The synthesis involves a highly regio- and stereoselective ring-closing metathesis of a bis-diene substrate to construct the macrocyclic triene core. Copper(I)-mediated
