71996-27-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 71996-27-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,9,9 and 6 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 71996-27:
(7*7)+(6*1)+(5*9)+(4*9)+(3*6)+(2*2)+(1*7)=165
165 % 10 = 5
So 71996-27-5 is a valid CAS Registry Number.

Formation of 2-phenylselenenylenones and 2-haloenones from enones. Mechanistic and synthetic aspects, X-ray crystal structures of intermediates

Engman, Lars,Toernroos, Karl Wilhelm

, p. 165 - 178 (2007/10/02)

The structure of trans-3-chloro-2-phenylselenenylcyclohexanone (1) was determined by X-ray diffraction.Although this and similar compounds were readily dehydrohalogenated to give vinylic selenides, they were ruled out as intermediates in the synthesis of

Reactions of α-Diazoketones with Phenylselenenyl Chloride. A new Synthesis of α-Chloro- and α-Phenylselenenyl-α,β-unsaturated Ketones

Buckley, Daniel J.,Kulkowit, Sunanta,McKervey, Anthony

, p. 506 - 507 (2007/10/02)

α-Diazoketones react with phenylselenenyl chloride at room temperature giving α-chloro-α-phenylselenenyl ketones; where structural considerations permit these adducts can be transformed via elimination reactions into α-chloro- or α-phenylselenenyl-α,β-uns
