131251-43-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 131251-43-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,2,5 and 1 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 131251-43:
(8*1)+(7*3)+(6*1)+(5*2)+(4*5)+(3*1)+(2*4)+(1*3)=79
79 % 10 = 9
So 131251-43-9 is a valid CAS Registry Number.

Acid Activation in Phenyliodine Dicarboxylates: Direct Observation, Structures, and Implications

Izquierdo, Susana,Essafi, Stéphanie,Del Rosal, Iker,Vidossich, Pietro,Pleixats, Roser,Vallribera, Adelina,Ujaque, Gregori,Lledós, Agustí,Shafir, Alexandr

, p. 12747 - 12750 (2016/10/13)

The use of the hypervalent iodine reagents in oxidative processes has become a staple in modern organic synthesis. Frequently, the reactivity of λ3 iodanes is further enhanced by acids (Lewis or Br?nsted). The origin of such activation, however, has remained elusive. Here, we use the common combination of PhI(OAc)2 with BF3·Et2O as a model to fully explore this activation phenomenon. In addition to the spectroscopic assessment of the dynamic acid-base interaction, for the first time the putative PIDA·BF3 complex has been isolated and its structure determined by X-ray diffraction. Consequences of such activation are discussed from a structural and electronic (DFT) points of views, including the origins of the enhanced reactivity.

Tandem radical reactions of isonitriles with 2-pyridonyl and other aryl radicals: Scope and limitations, and a first generation synthesis of (±)-camptothecin

Curran, Dennis P.,Liu, Hui,Josien, Hubert,Ko, Sung-Bo

, p. 11385 - 11404 (2007/10/03)

Photolysis of N-propargyl-6-halo-2-pyridones and related aromatic halides in the presence of aryl isonitriles provides tetra- and penta-cyclic products in a single step by a sequence of radical addition to the isonitrile followed by two cyclizations. The scope and limitations of the process are described along with a first generation synthesis of racemic camptothecin.
