124841-73-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 124841-73-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,8,4 and 1 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 124841-73:
(8*1)+(7*2)+(6*4)+(5*8)+(4*4)+(3*1)+(2*7)+(1*3)=122
122 % 10 = 2
So 124841-73-2 is a valid CAS Registry Number.

Synthesis of indoles from pyridinium salts. 7. Sterically hindered alkyl-3-nitropyridinium salts in the synthesis of indoles
Yurovskaya,Afanas'ev,Druzina,Bundel'
, p. 667 - 672 (1989)
The introduction of bulky alkyl substituents (iso-Pr,tert-Bu) into any positions of the starting 3-nitropyridinium salt only increases the reaction time and decreases the yields of the corresponding alkylindoles somewhat.
