Check Digit Verification of cas no

The CAS Registry Mumber 65565-08-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,5,6 and 5 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 65565-08:
(7*6)+(6*5)+(5*5)+(4*6)+(3*5)+(2*0)+(1*8)=144
144 % 10 = 4
So 65565-08-4 is a valid CAS Registry Number.

Photoenolization-induced oxirane ring opening in 2,5-dimethylbenzoyl oxiranes to form pharmaceutically promising indanone derivatives

Solomek, Tomas,Stacko, Peter,Tazhe Veetil, Aneesh,Pospisil, Tomas,Klan, Petr

experimental part, p. 7300 - 7309 (2011/01/12)

Irradiation of 2,5-dimethylbenzoyl oxiranes results in a relatively efficient and high-yielding formation of β-hydroxy functionalized indanones that structurally resemble biologically active pterosines. Nanosecond laser flash photolysis and quantum-chemical calculations based on density functional theory provided evidence that this photochemical transformation proceeds primarily via a photoenolization mechanism. Our study revealed considerable complexity of the mechanism and that structural modifications can significantly alter the reaction pathway and yield different products. The scope of this photochemical transformation for the synthesis of some pharmaceutically important compounds was investigated.
