82001-20-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 82001-20-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,0,0 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 82001-20:
(7*8)+(6*2)+(5*0)+(4*0)+(3*1)+(2*2)+(1*0)=75
75 % 10 = 5
So 82001-20-5 is a valid CAS Registry Number.

Synthesis of Lignan Lactones by Conjugate Addition of Thioacetal Carbanions to Butenolide

Pelter, Andrew,Ward, Robert S.,Satyanarayana, Panchagnula,Collins, Peter

, p. 643 - 647 (2007/10/02)

The conjugate addition of carbanions derived from arylbis(phenylthio)methanes to butenolide followed by trapping of the enolate anion so generated by a benzyl halide affords adducts (8) containing the basic lignan skeleton.Desulphurisation of these adducts by Raney nickel affords a short efficient synthesis of trans-dibenzylbutyrolactones and this route has been used to prepare enterolactone (9c) and an antitumour lignan (9b), derived from Bursera schlechtendalii.Treatment of the adducts (8) with heavy-metal salts induces cyclisation leading to arylnaphthalene lactones, including retrojusticidin B (13).

A CONVERGENT MERCURY MEDIATED LIGNAN SYNTHESIS

Pelter, Andrew,Ward, Robert S.,Satyanarayana, Panchagnula,Collins, Peter

, p. 571 - 572 (2007/10/02)

Bis(thiophenyl) derivatives of dibenzylbutyrolactones undergo cyclisation elimination and dehydrogenation when treated with mercuric trifluoroacetate.The process is a short, efficient synthesis of certain arylnaphthalene lignans.
