Check Digit Verification of cas no
The CAS Registry Mumber 109327-32-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,3,2 and 7 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 109327-32:
(8*1)+(7*0)+(6*9)+(5*3)+(4*2)+(3*7)+(2*3)+(1*2)=114
114 % 10 = 4
So 109327-32-4 is a valid CAS Registry Number.

An Approach to the Construction of Aromatic Steroids Using Electrocyclic Ring Closure
Gilchrist, Thomas L.,Stanford, John E.
, p. 225 - 230 (2007/10/02)
Methods for the construction of conjugated trienes in which the central double bond is part of a ring system have been investigated. 2-Chloro-3,4-dihydronaphthalen-1(2H)-one is treated with vinyl-lithium reagents to give the alcohols (10) which, when heat
