Check Digit Verification of cas no

The CAS Registry Mumber 1037586-23-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,7,5,8 and 6 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1037586-23:
(9*1)+(8*0)+(7*3)+(6*7)+(5*5)+(4*8)+(3*6)+(2*2)+(1*3)=154
154 % 10 = 4
So 1037586-23-4 is a valid CAS Registry Number.

Facile and general synthesis of quaternary 3-aminooxindoles

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

supporting information; experimental part, p. 2905 - 2908 (2009/05/30)

(Chemical Equation Presented) A novel approach to the valuable quaternary 3-aminooxindole skeleton is reported on the basis of intramolecular arylation of enolates of substituted amino acids. The reaction tolerates dialkyl- and arylalkylamines as well as a range of carbon substituents (primary and secondary alkyl, aryl). The cyclization of N-indolyl-substituted substrates is accompanied by direct C-H arylation of the indole, leading to indolo-fused benzodiazepines.
