Check Digit Verification of cas no

The CAS Registry Mumber 75470-72-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,4,7 and 0 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 75470-72:
(7*7)+(6*5)+(5*4)+(4*7)+(3*0)+(2*7)+(1*2)=143
143 % 10 = 3
So 75470-72-3 is a valid CAS Registry Number.

Rearrangement of 1-Azidoadamantane to 3-Aryl-4-azahomoadamantane in the Presence of Aluminum Chloride and Aromatic Substrates

Margosian, Daniel,Kovacic, Peter

, p. 877 - 880 (2007/10/02)

Reaction of 1-azidoadamantane (1) with aromatic substrates in the presence of aluminum chloride at 80 deg C for 1.25 h gave the corresponding 3-aryl-4-azahomoadamantane (2) in >90 percent yield.The reaction of 1 to 2 represents the first report of intermolecular aminoalkylation of aromatics in the benzene series, presumably from an imine intermediate.At 18 deg C, only 3-hydroxy-4-azahomoadamantane is obtained.Addition of water to the reaction system at 80 deg C yielded 1-phenyladamantane (4) as the major product.Mechanistic features are treated.
