702702-73-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 702702-73-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,0,2,7,0 and 2 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 702702-73:
(8*7)+(7*0)+(6*2)+(5*7)+(4*0)+(3*2)+(2*7)+(1*3)=126
126 % 10 = 6
So 702702-73-6 is a valid CAS Registry Number.

Rhodium(II)-catalyzed enantioselective C-H functionalization of indoles

Deangelis, Andrew,Shurtleff, Valerie W.,Dmitrenko, Olga,Fox, Joseph M.

supporting information; experimental part, p. 1650 - 1653 (2011/04/17)

A catalytic, enantioselective method for the C-H functionalization of indoles by diazo compounds has been achieved. With catalytic amounts of Rh 2(S-NTTL)4, the putative Rh-carbene intermediates from α-alkyl-α-diazoesters react with indoles at C(3) to provide α-alkyl-α-indolylacetates in high yield and enantioselectivity. From DFT calculations, a mechanism is proposed that involves a Rh-ylide intermediate with oxocarbenium character.
