Check Digit Verification of cas no

The CAS Registry Mumber 109049-84-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,0,4 and 9 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 109049-84:
(8*1)+(7*0)+(6*9)+(5*0)+(4*4)+(3*9)+(2*8)+(1*4)=125
125 % 10 = 5
So 109049-84-5 is a valid CAS Registry Number.

SYNTHESIS OF DIHYDRO-1H-PYRROLO- AND TETRAHYDROPYRIDOINDOLES VIA A MODIFIED MADELUNG REACTION

Verboom, W,Orlemans, E.O.M.,Berga, H.J.,Scheltinga, M.W.,Reinhoudt, D.N.

, p. 5053 - 5064 (2007/10/02)

1-(2-Methylphenyl)lactams 9, having different electron -withdrawing groups at the benzylicposition, cyclize under the influence of sodium hydride or potassium tert-butoxyde.Depending on the ring size of the lactam moiety dihydropyrrolo- (10), tetrahydropyridoindole (11), or dihydro-1H-1-benzazepine (12) derivatives are formed.Pyrroloindole 10c has been converted into the corresponding quione 15b.Starting from naphthaleneacetonitrile 20, prepared in 5 steps from 2,3-dichloronaphthoquinone, the 5,10-dioxo-1H-pyrollobenzindole 22 is obtained upon treatment with base and subsequent oxidation of the protected hydroquinone function with ceric ammonium nitrate.
