72863-23-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 72863-23-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,8,6 and 3 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 72863-23:
(7*7)+(6*2)+(5*8)+(4*6)+(3*3)+(2*2)+(1*3)=141
141 % 10 = 1
So 72863-23-1 is a valid CAS Registry Number.

, p. 1744 - 1749 (2007/10/02)

Treatment of allylic (+/-)-p-toluenesulfinate with tetrakis(triphenlphosphine)palladium in the presence of chiral phosphine ligands resulted in allylic sulfinate-sulfone rearrangements to give the corresponding optically active allylic sulfones in high op

Julia, Marc,Nel, Maurice,Righini, Anne,Uguen, Daniel

, p. 113 - 120 (2007/10/02)

The role of the palladium ligands on the yield and regioselectivity of the reaction of conjugated dienes with arenesulphinic acids (or of allylic acetates with sodium arenesulphinates) has been investigated.Arenesulphinic acids catalyse the isomerisation of allylic sulphones.
