Check Digit Verification of cas no

The CAS Registry Mumber 886853-78-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,6,8,5 and 3 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 886853-78:
(8*8)+(7*8)+(6*6)+(5*8)+(4*5)+(3*3)+(2*7)+(1*8)=247
247 % 10 = 7
So 886853-78-7 is a valid CAS Registry Number.

A highly selective tandem cross-coupling of gem-dihaloolefins for a modular, efficient synthesis of highly functionalized indoles

Fang, Yuan-Qing,Lautens, Mark

, p. 538 - 549 (2008/09/17)

(Chemical Equation Presented) A highly efficient method of indole synthesis using gem-dihalovinylaniline substrates and an organoboron reagent was developed via a Pd-catalyzed tandem intramolecular amination and an intermolecular Suzuki coupling. Aryl, alkenyl, and alkyl boron reagents are all successfully employed, making for a versatile modular approach. The reaction tolerates a variety of substitution patterns on the aniline leading to indoles with group at C2-C7. The orthogonal approach of the sequential copper- and palladium-mediated synthesis of 1,2-diarylindoles exploited the wide availability of diverse organoboron reagents.
