78727-20-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 78727-20-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,7,2 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 78727-20:
(7*7)+(6*8)+(5*7)+(4*2)+(3*7)+(2*2)+(1*0)=165
165 % 10 = 5
So 78727-20-5 is a valid CAS Registry Number.

A New Synthesis of 7,8,9,10-Tetrahydrocycloheptindol-6(5H)-ones

Kucklaender, Uwe,Toeberich, Hildegard

, p. 2238 - 2244 (2007/10/02)

p-Benzoquinone (5a) and methyl-p-benzoquinone (5b) react with N-aryl- and N-alkyl derivatives (4a-f) of 2-(aminomethylene)cyclohexanone to yield 2-hydroxy-5-alkyl- or -aryl-cyclohept-indol-6(5H)-ones 6a-j, the structure of which is proved by spectroscopic and chemical methods.A pathway for the reaction is given.By Fischer cyclisation of the phenylhydrazone cycloheptadiindole 16 is prepared from 6h.
