Check Digit Verification of cas no

The CAS Registry Mumber 7092-75-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,0,9 and 2 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 7092-75:
(6*7)+(5*0)+(4*9)+(3*2)+(2*7)+(1*5)=103
103 % 10 = 3
So 7092-75-3 is a valid CAS Registry Number.

Modern Friedel-Crafts chemistry. Part-271. Alkylation of benzene with 1-benzyl- and 1-phenylcyclohexanols in the presence of H 2SO4 and AlCl3/CH3NO2 catalysts

Khalaf, Ali A.,Awad, Ibrahim M.,El-Emary, Talaat I.,Abd El-Aal, Hassan A. K.

, p. 1018 - 1022 (2007/10/03)

The alkylation of benzyene with 1-benzylcyclohexanol (3) gave a mixture of 2,3-benzobicyclo[3.3.1]nona-2-ene (8, 79%) and cyclohexyldiphenylmethane (10, 21%) with AlCl3/CH3NO2 catalyst and a mixture of 1-benzylcyclohexene 5 (47.5%), 8 (8%), 10 (21.5%), 1-cyclopentyl-1,2- diphenylethane (12, 18%) and 1-benzyl-1-phenylcyclohexene (13, 4%) with H 2SO4 catalyst. Treatment of 3 with AlCl 3/CH3NO2 in petroleum ether gave a mixture of 5 (26%) and 8 (62%). Attempted alkylation of benzene with 1-phenylcyclohexanol (4) in the presence of either AlCl3/CH3NO2 or H2SO4 catalyst gave 1-(1-phenylcyclohexyl)-2- phenylcyclohexene (17) as sole product. Mechanistic interpretation of the results in terms of carbocation behaviour is offered.
