40426-44-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 40426-44-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,4,2 and 6 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 40426-44:
(7*4)+(6*0)+(5*4)+(4*2)+(3*6)+(2*4)+(1*4)=86
86 % 10 = 6
So 40426-44-6 is a valid CAS Registry Number.

Intramolecular trapping of an ylide intermediate in the reaction of1:CH2 with an allylic alcohol

Sobery, Warunee,DeLuca, Joann P.

, p. 3315 - 3316 (1995)

The reaction of 1:CH2, generated by the photolysis of CH2N2, with 2-methyl-3-buten-2-ol leads to the formation of several products including 4-methyl-3-penten-1-ol. This product is best explained as the result of rearrangement of an ylide intermediate.

Kinetics and mechanism of monomolecular heterolysis of commercial organohalogen compounds: XLI. Solvent effect on the rate of 3-methyl-3-chloro-1- butene solvolysis. Correlation analysis of solvation effects and role of solvent nucleophilicity

Ponomarev,Zaliznyi,Dvorko

, p. 1430 - 1436 (2008/02/03)

The kinetics of 3-methyl-3-chloro-1-butene solvolysis at 25°C in MeOH, EtOH, BuOH, i-BuOH, PentOH, 2-PrOH, 2-BuOH, HexOH, OctOH, t-BuOH, t-PentOH, cyclohexanol, and allyl alcohol was studied by the verdazyl method; v = k[C 5H9Cl], SN1 + E1 mechanism. The reaction rate shows a satisfactory correlation with the parameter of the solvent ionizing power E T and is independent of the solvent nucleophilicity. 2005 Pleiades Publishing, Inc.
