Check Digit Verification of cas no

The CAS Registry Mumber 60769-40-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,0,7,6 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 60769-40:
(7*6)+(6*0)+(5*7)+(4*6)+(3*9)+(2*4)+(1*0)=136
136 % 10 = 6
So 60769-40-6 is a valid CAS Registry Number.

Generation of Benzyne in the Thermal Decomposition of 2-Carboxyphenyl p-Toluenesulfonate

Luis, Santiago V.,Ferrer, Patrick,Burguete, M. Isabel

, p. 3808 - 3812 (2007/10/02)

The scope and the mechanism of the generation of 1,2-dehydrobenzene in the thermal decomposition of 2-carboxyphenyl p-toluenesulfonate and its salts (3) have been studied. 1,2-Dehydrobenzene, which can be trapped with dienic or nucleophilic reagents, is formed in a nonconcerted process with the intermediacy of a species C6H4CO2 (11) (probably benzoxet-2-one).A complex mixture of disalicylide, trisalicylide, and some other polysalicylides is formed, in the absence of trapping agents, by polymerization of this intermediate.
