Check Digit Verification of cas no

The CAS Registry Mumber 1229591-86-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,9,5,9 and 1 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1229591-86:
(9*1)+(8*2)+(7*2)+(6*9)+(5*5)+(4*9)+(3*1)+(2*8)+(1*6)=179
179 % 10 = 9
So 1229591-86-9 is a valid CAS Registry Number.

Rhenium(I)-catalyzed cyclization of silyl enol ethers containing a propargyl carboxylate moiety: Versatile access to highly substituted phenols

Saito, Kodai,Onizawa, Yuji,Kusama, Hiroyuki,Iwasawa, Nobuharu

supporting information; experimental part, p. 4716 - 4720 (2010/07/02)

Selective migration: The rhenium-catalyzed reaction of 2-siloxy-1-en-5-ynes containing an acyloxy substituent at the propargylic position gave highly substituted phenols in good yields (see scheme). Depending on the structure of the silyl enol ether, either nucleophilic addition of this moiety or 1,2acyloxy migration occurs to give two kinds of synthetically useful, substituted phenols.
