Check Digit Verification of cas no

The CAS Registry Mumber 116589-07-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,5,8 and 9 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 116589-07:
(8*1)+(7*1)+(6*6)+(5*5)+(4*8)+(3*9)+(2*0)+(1*7)=142
142 % 10 = 2
So 116589-07-2 is a valid CAS Registry Number.

Naruta, Yoshinori,Nagai, Naoshi,Maruyama, Kazuhiro

, p. 1143 - 1148 (2007/10/02)

The protected mitosane (23) is prepared in stereospecific manner.The key reactions included in the synthetic scheme are (i) Lewis acid-mediated Claisen-type rearrangement of the penta-2,4-dienyl aryl ether (10) to the penta-2,4-dienylphenol (11), (ii) the regioselective incorporation of the alkoxymethyl group at the 1-position of the pentadienyl side-chain in the protected pentadienylhydroquinone (12), and (iii) the stereospecific copper-catalysed double cyclization of the azido(penta-2,4-dienyl)quinone (15) to the 3H-pyrroloindole-5,8-dione (16) in one step.Subsequent stereospecific introduction of the aziridine ring furnishes the target compound (23).
