140239-80-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 140239-80-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,2,3 and 9 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 140239-80:
(8*1)+(7*4)+(6*0)+(5*2)+(4*3)+(3*9)+(2*8)+(1*0)=101
101 % 10 = 1
So 140239-80-1 is a valid CAS Registry Number.

Allylation of Alcohols and Carboxylic Acids with Allyl Acetate Catalyzed by [Ir(cod)2]+BF4- Complex

Nakagawa, Hideto,Hirabayashi, Tomotaka,Sakaguchi, Satoshi,Ishii, Yasutaka

, p. 3474 - 3477 (2004)

A facile method for the synthesis of allyl alkyl ethers from alcohols with allyl acetate was developed by the use of [Ir(cod)2] +BF4- complex. For instance, the reaction of allyl acetate with n-octyl alcohol in the presence of a catalytic amount of [Ir(cod)2]+BF4- complex afforded allyl octyl ether in quantitative yield. Allyl carboxylates were also prepared by the exchange reaction between carboxylic acids and allyl acetate in good yields. The [Ir(cod)2]+BF4- complex catalyzed the reaction of alkyl and aromatic amines with allyl acetate to lead to the corresponding allylamines in fair to good yields.
