305347-43-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 305347-43-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,5,3,4 and 7 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 305347-43:
(8*3)+(7*0)+(6*5)+(5*3)+(4*4)+(3*7)+(2*4)+(1*3)=117
117 % 10 = 7
So 305347-43-7 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 (2015/09/07)
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
