Check Digit Verification of cas no
The CAS Registry Mumber 7140-32-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,1,4 and 0 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 7140-32:
(6*7)+(5*1)+(4*4)+(3*0)+(2*3)+(1*2)=71
71 % 10 = 1
So 7140-32-1 is a valid CAS Registry Number.

2,3-Disubstituted indoles from olefins and hydrazines via tandem hydroformylation-Fischer indole synthesis and skeletal rearrangement
Linnepe, Petra,Schmidt, Axel M.,Eilbracht, Peter
, p. 302 - 313 (2007/10/03)
The tandem hydroformylation-Fischer indolisation protocol is used in the synthesis of 2,3-disubstituted indoles. After hydroformylation of selected olefins to form α-branched aldehydes in a one-pot procedure these are condensed with phenylhydrazine to give hydrazones. Upon acid-promoted [3,3]-sigmatropic rearrangement indolenine intermediates with quaternary centres in the 3-position are formed, which, after selective Wagner-Meerwein-type rearrangement of one of the substituents from the 3- to the 2-position, lead to 2,3-disubstituted indoles. Several olefins, bearing substituents with various functional groups, as well as cyclic olefinic systems are investigated. The Royal Society of Chemistry 2006.
