Check Digit Verification of cas no

The CAS Registry Mumber 74015-58-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,0,1 and 5 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 74015-58:
(7*7)+(6*4)+(5*0)+(4*1)+(3*5)+(2*5)+(1*8)=110
110 % 10 = 0
So 74015-58-0 is a valid CAS Registry Number.

Palladium(0)-catalyzed isomerization of α,β-epoxy ketones to β-diketones

Suzuki, M.,Watanabe, A.,Noyori, R.

, p. 230 - 236 (1988)

In the presence of catalytic amounts of tetrakis(triphenylphosphine)palladium(0) and 1,2-bis(diphenylphosphino)ethane, α,β-epoxy ketones isomerize to the corresponding β-diketones in high yields.Both open-chain and cyclic substrates can be used.Possible reaction mechanisms are discussed.
