112701-54-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 112701-54-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,7,0 and 1 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 112701-54:
(8*1)+(7*1)+(6*2)+(5*7)+(4*0)+(3*1)+(2*5)+(1*4)=79
79 % 10 = 9
So 112701-54-9 is a valid CAS Registry Number.

Stereoselective Bifunctionalization of Alkynes by Means of the Mercury(II) Salt-Iodine Combination

Barluenga, Jose,Martinez-Gallo, Jose M.,Najera, Carmen,Yus, Miguel

, p. 1017 - 1020 (2007/10/02)

The reaction of alkynes with iodine and mercury(II) salts (chloride, acetate, methanesulphonate, toluene-p-sulphonate, benzylsulphide, toluene-p-sulphinate, and thiocyanate) affords stereoselectively E-β-functionalized vinyl iodides resulting from the ionic addition of iodine and the mercury(II) salt anion.Unsymmetrical alkynes yield regiospecifically Markovnikov addition products.In the case of mercury(II) thiocyanate the reaction can be used also for the stereoselective preparation of E-1,2-dithiocyanatoalkenes.An ionic mechanism is proposed according to the observed regio- and stereochemistry.
