113681-39-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 113681-39-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,6,8 and 1 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 113681-39:
(8*1)+(7*1)+(6*3)+(5*6)+(4*8)+(3*1)+(2*3)+(1*9)=113
113 % 10 = 3
So 113681-39-3 is a valid CAS Registry Number.

Total synthesis of diverse carbogenic complexity within the resveratrol class from a common building block

Snyder, Scott A.,Breazzano, Steven P.,Ross, Audrey G.,Lin, Yunqing,Zografos, Alexandras L.

supporting information; experimental part, p. 1753 - 1765 (2009/07/25)

Although biomimetic approaches have proven capable of converting resveratrol (1) concurrently into many of the more complex oligomers produced by plants throughout the world (such as 2-10), methods to access single members of the family have proven far more difficult to identify. Herein is described a strategy-level solution based on the use of a common building block, one distinct from Nature's starting material, that can participate in a variety of highly selective, reagent-controlled reaction cascades. These endeavors have led to the controlled synthesis of 25 natural products and analogues, molecules whose architectures encompass nearlyall the carbogenic diversity of the resveratrol family.
