26944-56-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 26944-56-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,9,4 and 4 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 26944-56:
(7*2)+(6*6)+(5*9)+(4*4)+(3*4)+(2*5)+(1*6)=139
139 % 10 = 9
So 26944-56-9 is a valid CAS Registry Number.

Chemoenzymatic synthesis of the trans-dihydrodiol isomers of monosubstituted benzenes via anti-benzene dioxides

Boyd, Derek R.,Sharma, Narain D.,Llamas, Nuria M.,O'Dowd, Colin R.,Allen, Christopher C. R.

, p. 2208 - 2217 (2008/02/09)

Enantiopure cis-2,3-dihydrodiols, available from dioxygenase-catalysed cis-dihydroxylation of monosubstituted benzene substrates, have been used as synthetic precursors of the corresponding trans-3,4-dihydrodiols. The six-step chemoenzymatic route from ci

Resolution of trans-1,2-Dihydroxy-1,2-dihydrobenzene for the Preparation of Optically Pure Benzene Diol Epoxides. Preparation of Bromo- and Chlorobenzene Diol Epoxides

Ganey, Michael V.,Padykula, Robert E.,Berchtold, Glenn A.,Braun, Andrew G.

, p. 2787 - 2793 (2007/10/02)

The resolution of (+/-)-trans-1,2-dihydroxy-1,2-dihydrobenzene has been accomplished by esterase-catalysed hydrolysis of diacetate (+/-)-5.Peracid epoxidation of (+)-2 and (-)-2 gave diol epoxides (+)-3 and (-)-3, respectively.The synthesis of d
