Check Digit Verification of cas no
The CAS Registry Mumber 18992-68-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,9,9 and 2 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 18992-68:
(7*1)+(6*8)+(5*9)+(4*9)+(3*2)+(2*6)+(1*8)=162
162 % 10 = 2
So 18992-68-2 is a valid CAS Registry Number.

Acid-catalyzed rearrangement of 6-bromo-2,4-dimethyl-4(phenylamino)cyclohexa-1,4-dienone (1, a quinamine) in aqueous methanol gives, from a so-called quinamine rearrangement, 4'-amino-6-bromo-2,4-dimethyldiphenyl ether (2) and a number of byproducts.The r
Generation and Rearrangement of 4aH-carbazoles

The benzotriazoles (12a-c) bearing ortho-blocked 1-aryl substituents have been decomposed thermally by flash vacuum pyrolysis, and photochemically by irradiation in acetonitrile at 254 nm.The pyrolyses are complex giving mainly mono- and di-methylcarbazoles from (12a), di- and trimethylcarbazoles from (12b), and a tetra- and a penta-methylcarbazole from (12c).All of these products could be formed by generation of 4aH-carbazole intermediates (24) with subsequent thermally-allowed sigmatropic rearrangements (Scheme 6).The photolyses give a different set of products consisting mainly of the cyclopentaquinolines (27a-c) from (12a-c), respectively.These products could be formed from the same 4aH-carbazoles (24) which now undergo photochemical, aza-di-?-methane, rearrangements to give intermediates (29) and hence products (27) (Scheme 7).The 4a-methyl intermediate (29c) is intercepted as the adduct (30) in an extended cycloaddition reaction with acrylonitrile.Key reaction products were synthesized by independent methods.
