698-93-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 698-93-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,9 and 8 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 698-93:
(5*6)+(4*9)+(3*8)+(2*9)+(1*3)=111
111 % 10 = 1
So 698-93-1 is a valid CAS Registry Number.

An improved synthesis of dialkylcyclopropenones
Netland, Kjetil Andreas,Gundersen, Lise-Lotte,Rise, Frode
, p. 1767 - 1777 (2007/10/03)
Dialkylcyclopropenones are formed in high yields when alkynes are treated with chloroform-butyllithium in THF at - 78 °C followed by acidic hydrolysis of the dichlorocyclopropene intermediates at low temperatures.
