Calculate Digit Verification of CAS Registry Number 1313484-36:
(9*1)+(8*3)+(7*1)+(6*3)+(5*4)+(4*8)+(3*4)+(2*3)+(1*6)=134
134 % 10 = 4
So 1313484-36-4 is a valid CAS Registry Number.

Synthesis of the B-seco limonoid core scaffold

Bruss, Hanna,Schuster, Hannah,Martinez, Remi,Kaiser, Markus,Antonchick, Andrey P.,Waldmann, Herbert

, p. 194 - 208 (2014/02/14)

Synthetic investigations towards the structurally complex and highly decorated framework of B-seco limonoid natural products by means of a [3,3]-sigmatropic rearrangement are described. Detailed model studies reveal, that an Ireland-Claisen rearrangement can be employed to construct the central C9-C10 bond thereby giving access to the B-seco limonoid scaffold. However, application of the developed strategy ended up failing in more complex and sterically demanding systems.
