The CAS Registry Mumber 1428771-11-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,8,7,7 and 1 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1428771-11:
(9*1)+(8*4)+(7*2)+(6*8)+(5*7)+(4*7)+(3*1)+(2*1)+(1*1)=172

Enantioselective synthesis of spiro[cyclohexane-1,3′-indolin]- 2′-ones containing multiple stereocenters via organocatalytic Michael/aldol cascade reactions

Ghosh, Arun K.,Zhou, Bing

supporting information, p. 2311 - 2314 (2013/06/26)

Organocatalytic reactions of 3-olefinic oxindoles and pentane-1,5-dial were investigated to provide access to substituted spirocyclohexane oxindoles via Michael/aldol cascade reactions. Of particular interest, we have examined the stereochemical outcome o
