125288-33-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 125288-33-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,2,8 and 8 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 125288-33:
(8*1)+(7*2)+(6*5)+(5*2)+(4*8)+(3*8)+(2*3)+(1*3)=127
127 % 10 = 7
So 125288-33-7 is a valid CAS Registry Number.

An Effective Method for the Construction of Esters Using Cs2CO3 as Oxygen Source

Ren, Lanhui,Wang, Lianyue,Lv, Ying,Li, Guosong,Gao, Shuang

, p. 5172 - 5175 (2015)

An effective method for the construction of esters from acyl chloride and halohydrocarbon using Cs2CO3 as an oxygen source was achieved for the first time. The methodology has a wide scope of substrates and can be scaled up. The study of a preliminary reaction mechanism demonstrated that the O in the products comes from Cs2CO3 and this esterification proceeds through a free radical reaction. It was also found that CO2 can also be used in this esterification reaction as an oxygen source.

Copper-catalyzed Csp3-O cross-coupling of unactivated alkyl halides with organic peroxides

Chen, Huan-Huan,Wang, Guang-Zu,Han, Jin,Xu, Meng-Yu,Zhao, Yong-Qiang,Xu, Hua-Jian

, p. 212 - 217 (2014/01/06)

An efficient Cu-catalyzed Csp3-O coupling of peroxides with haloalkanes is described. High yields of products were achieved under mild conditions. Significantly, in addition to primary alkyl halides, secondary alkyl halogenated hydrocarbons could also be applied to this system. The new reaction system could tolerate a wide range of organic peroxides.

A new synthetic method for haloalkyl carboxylic esters from the radical ring cleavage of cyclic acetals with haloform

Hai-Xia, Lin,Liang-Heng, Xu,Nai-Ju, Huang

, p. 303 - 306 (2007/10/03)

A one-pot reaction of cyclic acetals with haloform catalyzed by AIBN(2,2'-azobisisobutyronitrile) provides a novel convenient way to prepare directly haloalkyl carboxylic esters in good yields.
