220649-63-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 220649-63-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,6,4 and 9 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 220649-63:
(8*2)+(7*2)+(6*0)+(5*6)+(4*4)+(3*9)+(2*6)+(1*3)=118
118 % 10 = 8
So 220649-63-8 is a valid CAS Registry Number.

Synthesis and cycloaromatization kinetics of aromatic allene enynes
Dopico, Pablo G.,Finn
, p. 29 - 62 (2007/10/03)
Aryl- and cyclopropyl-substituted allene enynes were prepared by a double olefination procedure from various aldehydes; and their cycloaromatization reactions were subjected to kinetics measurements in methanol and 1,4-cyclohexadiene solvents. The results
