The CAS Registry Mumber 150254-04-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,0,2,5 and 4 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 150254-04:
(8*1)+(7*5)+(6*0)+(5*2)+(4*5)+(3*4)+(2*0)+(1*4)=89
89 % 10 = 9
So 150254-04-9 is a valid CAS Registry Number.

Intramolecular Arene Trapping of Pyran-4-one Derived Zwitterions: A Two-Step Synthesis of Tetrahydrobenzinden-1-ones

West, F. G.,Willoughby, Duke W.

, p. 3796 - 3797 (1993)

Pyran-4-ones bearing pendant arene traps undergo efficient photolytic conversion to transient oxyallyl zwitterions, which then cyclize onto the arene in an intramolecular electrophilic aromatic substitution to yield tetrahydrobenzindenones.
