Check Digit Verification of cas no

The CAS Registry Mumber 81089-20-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,0,8 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 81089-20:
(7*8)+(6*1)+(5*0)+(4*8)+(3*9)+(2*2)+(1*0)=125
125 % 10 = 5
So 81089-20-5 is a valid CAS Registry Number.

Preparation of oxacycloalkenones

-

, (2008/06/13)

Oxacycloalkenones are prepared by reacting a cycloalkenone with a base in the presence of a dioxygen source in a suitable solvent and isolating the desired product. 1-Hydroxy 2-oxa-3-oxo-Δ4 steroids are convenient synthetic precursors to 2-oxa-

Superoxide-, tert-Butoxide-, and Hydroxide-Mediated Autoxidation of 3-Oxo-Δ4 Steroids in Aprotic Media

Frimer, Aryeh A.,Gilinsky-Sharon, Pessia,Hameiri, Judith,Aljadeff, Gladis

, p. 2818 - 2819 (2007/10/02)

The course of the base-catalyzed autoxidation of 3-oxo-Δ4 steroids in aprotic media differs sharply both in yield and product distribution from that reported for protic solvents and involves the oxygenation of the kinetic dienolate.
