855308-39-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 855308-39-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,5,3,0 and 8 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 855308-39:
(8*8)+(7*5)+(6*5)+(5*3)+(4*0)+(3*8)+(2*3)+(1*9)=183
183 % 10 = 3
So 855308-39-3 is a valid CAS Registry Number.

Mono- and diboronates derived from tridentate ONO ligands and arylboronic acids

Barba, Victor,Vázquez, Julián,López, Fernando,Santillan, Rosa,Farfán, Norberto

, p. 2351 - 2357 (2008/10/09)

The syntheses of eight [4.3.0] heterobicyclic boronates containing a N → B coordinative bond are described. The monomeric compounds were prepared by reaction of arylboronic acids with a tridentate ligand having the ONO donor set of atoms. It was shown that substituents at the para-position of the B-phenyl moiety transmit electronic effects to the CN bond which in turn is polarized by formation of the N → B coordination bond. At the same time, related tridentate ligands were also reacted with 1,4-benzenediboronic acid in order to prepare benzene diboron complexes. The structure of this type of compounds was confirmed by X-ray analysis for one of the derivatives.
