Check Digit Verification of cas no

The CAS Registry Mumber 228721-40-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,8,7,2 and 1 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 228721-40:
(8*2)+(7*2)+(6*8)+(5*7)+(4*2)+(3*1)+(2*4)+(1*0)=132
132 % 10 = 2
So 228721-40-2 is a valid CAS Registry Number.

Intramolecular radical allylation with allylic sulfones a synthesis of (±)-botryodiplodin

Nouguier, Robert,Gastaldi, Stephane,Stien, Didier,Bertrand, Michele,Renaud, Philippe

, p. 3371 - 3374 (1999)

Isopropenyl-5-membered-ring acetal or lactone are potential precursors of (±)-botryodiplodin (1). Several pathways, involving 5-exo-trig ring closure onto allylic sulfones, have been investigated. The iodine atom transfer methodology allowed the preparati

Synthesis of (±)- and (-)-botryodiplodin using stereoselective radical cyclizations of acyclic esters and acetals

Nouguier, Robert,Gastaldi, Stephane,Stien, Didier,Bertrand, Michele,Villar, Felix,Andrey, Olivier,Renaud, Philippe

, p. 3005 - 3018 (2007/10/03)

Three different routes for the stereoselective synthesis of botryodiplodin have been investigated. The intramolecular allylation of acetals proved to be unsatisfactory due to unstable intermediates and poor stereocontrol. Zard intramolecular radical allyl
