99050-43-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 99050-43-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,0,5 and 0 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 99050-43:
(7*9)+(6*9)+(5*0)+(4*5)+(3*0)+(2*4)+(1*3)=148
148 % 10 = 8
So 99050-43-8 is a valid CAS Registry Number.

Enantioselective Ruthenium-Catalyzed Benzocyclobutenone-Ketol Cycloaddition: Merging C-C Bond Activation and Transfer Hydrogenative Coupling for Type II Polyketide Construction

Ambler, Brett R.,Turnbull, Ben W. H.,Suravarapu, Sankar Rao,Uteuliyev, Maulen M.,Huynh, Nancy O.,Krische, Michael J.

supporting information, p. 9091 - 9094 (2018/08/03)

The first enantioselective intermolecular metal-catalyzed cycloadditions of benzocyclobutenones via C-C bond oxidative addition are described. In the presence of a ruthenium(0) complex modified by (R)-DM-SEGPHOS, tetralone-derived ketols and benzocyclobutenones combine to form cycloadducts with complete regio- and diastereoselectivity and high enantioselectivity. Using this method, the "bay region" substructure of the angucycline natural product arenimycin was prepared.
