Check Digit Verification of cas no

The CAS Registry Mumber 80767-12-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,7,6 and 7 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 80767-12:
(7*8)+(6*0)+(5*7)+(4*6)+(3*7)+(2*1)+(1*2)=140
140 % 10 = 0
So 80767-12-0 is a valid CAS Registry Number.

Lipase-mediated selective acetylation of primary alcohols in ethyl acetate

de Souza, Ernane C.,Romero-Ortega, Moises,Olivo, Horacio F.

supporting information, p. 287 - 290 (2017/12/29)

An environmental friendly process to selectively acetylate primary alcohols was demonstrated. The esterification process consists of treatment of a primary alcohol in the presence of immobilized C. antarctica lipase (Novozyme-435) in ethyl acetate at room temperature. Primary alcohols were acetylated in the presence of secondary alcohols and phenols.

Decarboxylative Csp3-Csp3 coupling for benzylation of unstable ketone enolates: Synthesis of: P -(acylethyl)phenols

Wang, Sasa,Chen, Xinzheng,Ao, Qiaoqiao,Wang, Huifei,Zhai, Hongbin

, p. 9454 - 9457 (2016/07/29)

A new decarboxylative Csp3-Csp3 coupling approach for the benzylation of ketone enolates has been developed. A variety of raspberry ketone derivatives were conveniently synthesized in good to excellent yields under mild conditions. A crossover reaction shed light on the mechanism of this tandem reaction.

Efficient approach for the chemoselective acetylation of alcohols catalyzed by a novel metal oxide nanocatalyst CuO-ZnO

Albadi, Jalal,Alihosseinzadeh, Amir,Mardani, Mehdi

, p. 308 - 313 (2015/09/28)

A new method has been developed for the chemoselective acetylation of alcohols with acetic anhydride in the presence of phenols using a novel, recyclable CuO-ZnO nanocatalyst. The catalyst was synthesized using the co-precipitation method and characterized by N2 adsorption-desorption, X-ray diffraction, scanning electron microscopy, transmission electron microscopy and energy dispersion scanning analyses. Furthermore, this catalyst could be recycled up to six times without significant loss in its activity.
