1158201-53-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1158201-53-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,5,8,2,0 and 1 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1158201-53:
(9*1)+(8*1)+(7*5)+(6*8)+(5*2)+(4*0)+(3*1)+(2*5)+(1*3)=126
126 % 10 = 6
So 1158201-53-6 is a valid CAS Registry Number.

First example of C-3 alkylation of indoles with activated azetidines catalyzed by indium(III) bromide
Yadav,Subba Reddy,Narasimhulu,Satheesh
, p. 727 - 730 (2009)
Indoles undergo smooth alkylation with N-tosylazetidines in the presence of indium(III) bromide in dichloroethane under mild conditions to produce the corresponding C-3 substituted indole derivatives in good to high yields and with high selectivity. This
