1428901-69-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1428901-69-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,8,9,0 and 1 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1428901-69:
(9*1)+(8*4)+(7*2)+(6*8)+(5*9)+(4*0)+(3*1)+(2*6)+(1*9)=172
172 % 10 = 2
So 1428901-69-2 is a valid CAS Registry Number.

A convenient method for lactonization of α-allyl esters using iodine in dimethylsulphoxide

Nawghare, Beena R.,Gaikwad, Sunil V.,Pawar, Bharati V.,Lokhande, Pradeep D.

, p. 469 - 473 (2014)

A simple method for the synthesis of α-γ-disubstituted-γ-butyrolactones by cyclization of α-allyl esters using iodine in dimethylsulphoxide is reported. This method is efficient and operationally simple in comparison to methods using transition metal comp

First iodine-catalyzed deallylation of reactive allyl methylene esters

Nawghare, Beena R.,Lokhande, Pradeep D.

, p. 1955 - 1963 (2013/06/05)

C-Allyl cleavage has been developed using the inexpensive and mild reagent iodine in dimethylsulfoxide. A variety of compounds with active methylene groups were C-deallylated using this reagent. This method is efficient and operationally simple in comparison to the methods using transition-metal complexes. Supplemental materials are available for this article.
