Check Digit Verification of cas no

The CAS Registry Mumber 26697-95-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,6,9 and 7 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 26697-95:
(7*2)+(6*6)+(5*6)+(4*9)+(3*7)+(2*9)+(1*5)=160
160 % 10 = 0
So 26697-95-0 is a valid CAS Registry Number.

Silver-promoted, palladium-catalyzed direct arylation of cyclopropanes: Facile access to spiro 3,3′-cyclopropyl oxindoles

Ladd, Carolyn L.,Sustac Roman, Daniela,Charette, André B.

supporting information, p. 1350 - 1353 (2013/05/09)

The Pd-catalyzed, Ag(I)-mediated intramolecular direct arylation of cyclopropane C-H bonds is described. Various spiro 3,3′-cyclopropyl oxindoles can be obtained in good to excellent yields from easily accessible 2-bromoanilides. The kinetic isotope effect was determined and epimerization studies were conducted, suggesting that the formation of a putative Pd-enolate is not operative and that the reaction proceeds via a C-H arylation pathway.
