547739-18-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 547739-18-4 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, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 547739-18:
(8*5)+(7*4)+(6*7)+(5*7)+(4*3)+(3*9)+(2*1)+(1*8)=194
194 % 10 = 4
So 547739-18-4 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
