6502-18-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 6502-18-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,5,0 and 2 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 6502-18:
(6*6)+(5*5)+(4*0)+(3*2)+(2*1)+(1*8)=77
77 % 10 = 7
So 6502-18-7 is a valid CAS Registry Number.

Superoxide mediated isomerization of 4-aryl-but-1-ynes to 1-aryl-1,3-butadienes
Khan, Faiz Ahmed,Budanur, Basavaraj M.
, p. 7600 - 7607 (2015)
A new role of superoxide ion in the isomerization of homobenzylic acetylenes leading to 1-aryl-1,3-butadienes is reported. The unconventional reagent KO2 is found to be superior in performing this kind of isomerization over other the commonly u
