Check Digit Verification of cas no

The CAS Registry Mumber 74973-40-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,9,7 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 74973-40:
(7*7)+(6*4)+(5*9)+(4*7)+(3*3)+(2*4)+(1*0)=163
163 % 10 = 3
So 74973-40-3 is a valid CAS Registry Number.

Reactions of Aryl Cyclopropyl Ketones. A New Synthesis of Aryl Tetralones

Murphy, William S.,Wattanasin, Sompong

, p. 2920 - 2926 (2007/10/02)

Aryl cyclopropyl ketones (2) cyclise to 1-tetralones (3) in the presence of a variety of acid catalysts under mild conditions.Open-chain carbinols (4) are also formed.The ratio of (3) to (4) is dependent on the aryl ring substituents.A cationic mechanism is proposed.Cyclopropyl ketones (1) do not react.Stereoelectronic factors involved in the reactivity of the rigig cyclopropyl ketone (12) are discussed.The reactions of selected phenolic cyclopropyl ketones have been investigated as anionic counterparts to the acid-catalysed reactions.No reaction is observed.

TRAPPING THE INTERMEDIATE INVOLVED IN THE INTRAMOLECULAR CYCLISATION OF CYCLOPROPYL KETONES. A CONVENIENT PREPARATION OF OPEN-CHAIN γ-HYDROXY KETONES.

Murphy, William S.,Wattanasin, Sompong

, p. 3517 - 3520 (2007/10/02)

The concerted mechanism for the stannic chloride catalysed cyclisation of aryl cyclopropyl ketones is disproved by trapping the intermediate.The reaction provides a facile route to γ-hydroxyketones.

A NEW CYCLISATION INVOLVING CYCLOPROPYL KETONES. A SHORT ROUTE TO 1-ARYLTETRALONES.

Murphy, William S.,Wattanasin, Sompong

, p. 1887 - 1890 (2007/10/02)

Activated aryl aroylcyclopropanes cyclise with Lewis acids under mild conditons to 1-aryltetralones.
