309248-63-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 309248-63-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,9,2,4 and 8 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 309248-63:
(8*3)+(7*0)+(6*9)+(5*2)+(4*4)+(3*8)+(2*6)+(1*3)=143
143 % 10 = 3
So 309248-63-3 is a valid CAS Registry Number.

Enantioselective synthesis of tetraponerines by Pd- and Ru-catalyzed domino reactions
Stragies,Blechert
, p. 9584 - 9591 (2007/10/03)
An enantioselective synthesis of tetraponerines T4, T6, T7, and T8 in 24-36% overall yield is described. Key steps in this synthesis are a Pd-catalyzed domino allylation and a Ru-catalyzed ring rearrangement. The effect of different substituents on the eq
