Check Digit Verification of cas no

The CAS Registry Mumber 72012-54-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,0,1 and 2 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 72012-54:
(7*7)+(6*2)+(5*0)+(4*1)+(3*2)+(2*5)+(1*4)=85
85 % 10 = 5
So 72012-54-5 is a valid CAS Registry Number.

The Sensitized Photooxidation of Methoxycycloheptatrienes. The Synthesis of α-, β-, and γ-Tropolones

Yagihara, Morio,Kitahara, Yoshio,Asao, Toyonobu

, p. 236 - 238 (2007/10/02)

The sensitized photooxidation of 7-methoxycycloheptatriene (7-methoxytropilidene) afforded cycloadduct (2), tropone, benzaldehyde and their 2-methoxy derivatives.Thermal isomerization of 2 followed by the treatment with alumina yielded 4-methoxytropone.The photooxidation of 1-methoxytropilidene gave 4-hydroxytropone and o-methoxybenzaldehyde, and the photooxidation of 3-methoxytropilidene followed by the treatment with triethylamine afforded 3-methoxytropone, tropone, and o-methoxybenzaldehyde.Characterization of the products and the mechanisms of the reactions are discussed.
