478309-03-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 478309-03-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,8,3,0 and 9 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 478309-03:
(8*4)+(7*7)+(6*8)+(5*3)+(4*0)+(3*9)+(2*0)+(1*3)=174
174 % 10 = 4
So 478309-03-4 is a valid CAS Registry Number.

Enantioselective synthesis of 6-nor-fluvirucinin B1
Baltrusch, Anne W.,Bracher, Franz
, p. 1724 - 1726 (2007/10/03)
An enantioselective synthesis of the 6-nor-derivative 3 of the antiviral macrocyclic lactam fluvirucinin B1 (2) is presented. Key steps are two regioselective ring opening reactions of chiral epoxides, and a ring-closing metathesis with Grubbs'
