142631-56-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 142631-56-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,6,3 and 1 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 142631-56:
(8*1)+(7*4)+(6*2)+(5*6)+(4*3)+(3*1)+(2*5)+(1*6)=109
109 % 10 = 9
So 142631-56-9 is a valid CAS Registry Number.

A more convenient and general procedure for O-monobenzylation of diols via Stannylenes: A critical reevaluation of the Bu2SnO method

Simas, Alessandro B. C.,Pais, Karla C.,Da Silva, Angelo A. T.

, p. 5426 - 5428 (2003)

A more consistent, straightforward, and economical protocol for generation of stannylene species and their reaction with BnBr leading to products of O-monobenzylation of diols has been set. It has shown to be specially indicated for substrates bearing vicinal trans 1,2-diol moieties on cyclohexane backbones, which are more resistant to these transformations. Such protocol has been successfully applied to myo-inositol derivatives and acyclic diols.

Direct selective and controlled protection of multiple hydroxyl groups in polyols via iterative regeneration of stannylene acetals

Simas, Alessandro B.C.,da Silva, Angelo A.T.,dos Santos Filho, Tarcizio J.,Barroso, Pedro T.W.

supporting information; experimental part, p. 2744 - 2746 (2009/09/25)

A direct selective protection (O-benzylation) of two or more hydroxyl groups in polyols displaying diverse structural patterns was made possible by the establishment of conditions that enable an efficient turnover for the Bu2Sn group, initially

Synthesis and Tritium Radiolabelling of Fluorinated Analogues of myo-Inositol

Offer, John L.,Voorheis, H. Paul,Metcalfe, James C.,Smith, Gerry A.

, p. 953 - 960 (2007/10/02)

Syntheses have been developed for a set of six myo-inositol analogues from myo-inositol in which single hydroxy groups have been replaced by fluorine (monodeoxy-fluoro-myo-inositols).Except for 2-deoxy-2-fluoro-myo-inositol 32 and 1D-4-deoxy-4-fluoro-myo-
