136144-59-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 136144-59-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,1,4 and 4 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 136144-59:
(8*1)+(7*3)+(6*6)+(5*1)+(4*4)+(3*4)+(2*5)+(1*9)=117
117 % 10 = 7
So 136144-59-7 is a valid CAS Registry Number.

Water-Soluble Pd-Imidate Complexes: Broadly Applicable Catalysts for the Synthesis of Chemically Modified Nucleosides via Pd-Catalyzed Cross-Coupling

Gayakhe, Vijay,Ardhapure, Ajaykumar,Kapdi, Anant R.,Sanghvi, Yogesh S.,Serrano, Jose Luis,García, Luis,Pérez, Jose,García, Joaquím,Sánchez, Gregorio,Fischer, Christian,Schulzke, Carola

(Figure Presented) A broadly applicable catalyst system consisting of water-soluble Pd-imidate complexes has been enployed for the Suzuki-Miyaura cross-coupling of four different nucleosides in water under mild conditions. The efficient nature of the catalyst system also allowed its application in developing a microwave-assisted protocol with the purpose of expediting the catalytic reaction. Preliminary mechanistic studies, assisted by catalyst poison tests and stoichiometric tests performed using an electrospray ionization spectrometer, revealed the possible presence of a homotopic catalyst system.

PALLADIUM CATALYZED COUPLING REACTION FOR THE SYNTHESIS OF C-5 ARYL AND HETEROARYL SUBSTITUTED 2'-DEOXYCYTIDINE

Hassan, Mohamed E.

, p. 1295 - 1299 (2007/10/02)

Cytosine nucleosides substituted at C-5 with differently substituted aryls and heteroaryls have been prepared via a palladium catalyzed reaction utilizing 5-chloromercuri or acetoxymercuri nucleosides and haloarenes or heteroarenes.
