22543-72-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 22543-72-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,5,4 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 22543-72:
(7*2)+(6*2)+(5*5)+(4*4)+(3*3)+(2*7)+(1*2)=92
92 % 10 = 2
So 22543-72-2 is a valid CAS Registry Number.

Transition-metal catalysts are powerful tools for carbon-carbon bond-forming reactions that are difficult to achieve using native enzymes. Enzymes that exhibit inherent selectivities and reactivities through host-guest interactions have inspired widesprea

Solvent control of product diversity in palladium-catalyzed addition of arylboronic acid to aryl aldehydes

Das, Tuluma,Chakraborty, Amarnath,Sarkar, Amitabha

supporting information, p. 5174 - 5178 (2014/12/10)

In Pd-catalyzed arylboronic acid addition to aryl aldehydes, the expected carbinol or asymmetrical ether can be obtained as the major product by altering aqueous solvent composition. Exploiting this methodology with 2-formylbiphenyls as reaction partner, a fluorene scaffold can be readily constructed in two steps.
