Check Digit Verification of cas no

The CAS Registry Mumber 1169877-41-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,6,9,8,7 and 7 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1169877-41:
(9*1)+(8*1)+(7*6)+(6*9)+(5*8)+(4*7)+(3*7)+(2*4)+(1*1)=211
211 % 10 = 1
So 1169877-41-1 is a valid CAS Registry Number.

A robust, efficient catalyst system for enolate arylation leading to quaternary 3-aminooxindoles

Watson, Emma L.,Marsden, Stephen P.,Raw, Steven A.

, p. 3318 - 3320 (2009)

A catalyst screening programme has revealed that a combination of Pd(0) and the N-heterocyclic carbene ligand SIPr forms a particularly robust and efficient catalyst for the formation of important quaternary 3-aminooxindoles via intramolecular enolate ary
