120534-02-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 120534-02-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,5,3 and 4 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 120534-02:
(8*1)+(7*2)+(6*0)+(5*5)+(4*3)+(3*4)+(2*0)+(1*2)=73
73 % 10 = 3
So 120534-02-3 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 (2007/10/02)
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.
