87422-12-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87422-12-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,4,2 and 2 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 87422-12:
(7*8)+(6*7)+(5*4)+(4*2)+(3*2)+(2*1)+(1*2)=136
136 % 10 = 6
So 87422-12-6 is a valid CAS Registry Number.

CIS-TRIS--?-HOMOBENZENE - SYNTHESIS AND THERMOLYSIS
Maas, M.,Lutterbeck, M.,Hunkler, D.,Prinzbach, H.
, p. 2143 - 2146 (1983)
The cis-tris--?-homobenzene 7 has been synthesised.From vapour phase thermolyses (400-500 deg C) it is concluded, that the ?2s+?2s+?2s>-cycloreversion reaction is - at most - only a minor pathway in the thermal stabilisation of 7.
