220650-25-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 220650-25-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,6,5 and 0 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 220650-25:
(8*2)+(7*2)+(6*0)+(5*6)+(4*5)+(3*0)+(2*2)+(1*5)=89
89 % 10 = 9
So 220650-25-9 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
