79827-83-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 79827-83-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,8,2 and 7 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 79827-83:
(7*7)+(6*9)+(5*8)+(4*2)+(3*7)+(2*8)+(1*3)=191
191 % 10 = 1
So 79827-83-1 is a valid CAS Registry Number.

Substituent Effect Behavior in the Antiaromatic Inden-1-yl Cation System

Friedrich, Edwin C.,Tam, Teresa M.

, p. 315 - 319 (2007/10/02)

Studies of the rate-accelerating effects in solvolysis produced by 5-methyl and 5-methoxy substituents on the benzene ring and a 3-methyl substituent on the double bond of the inden-1-yl 3,5-dinitrobenzolate system have been carried out.In both 80percent aqueous acetone and in 2,2,2-trifluoroethanol, the rate accelerations observed in the inden-1-yl system were approximately the same as those found in model cyclopenten-3-yl and indan-1-yl systems.From these results, it is concluded that delocalization of charge into both the benzene ring and double bond of the 8?-electron inden-1-yl carbocation is taking place and is apparently undiminished by antiaromatic effects.
