Check Digit Verification of cas no

The CAS Registry Mumber 1027994-13-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,7,9,9 and 4 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1027994-13:
(9*1)+(8*0)+(7*2)+(6*7)+(5*9)+(4*9)+(3*4)+(2*1)+(1*3)=163
163 % 10 = 3
So 1027994-13-3 is a valid CAS Registry Number.

Cyclization pathways of a (Z)-stilbene-derived bis(orthoquinone monoketal)

Feldman, Ken S.

, p. 4983 - 4990 (2007/10/03)

Lead tetraacetate mediated oxidation of a (Z)-bisphenolic stilbene derivative affords a bis(orthoquinone monoketal) product. Thermolysis studies of this highly unsaturated dione reveal that sigmatropic hydrogen shifts, followed by either of two distinct solvolytic ring closures, constitute the predominate reaction pathways under heating. No evidence for a desired 6π electron electrocyclization was forthcoming.
