Check Digit Verification of cas no

The CAS Registry Mumber 17890-65-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,8,9 and 0 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 17890-65:
(7*1)+(6*7)+(5*8)+(4*9)+(3*0)+(2*6)+(1*5)=142
142 % 10 = 2
So 17890-65-2 is a valid CAS Registry Number.

Photochemical Reactions of o-Alkenylphenols and 1-Alkenyl-2-naphthol with Alkylamines: Amination via Photoinduced Proton Transfer

Yasuda, Masahide,Sone, Tatsuya,Tanabe, Kimiko,Shima, Kensuke

, p. 459 - 464 (2007/10/02)

Irradiation of o-alkenylphenols 1a-c and 2a-e in the presence of alkylamines gave o-(1-alkylaminoalkyl)phenols 4a-n and 5a-e in relatively good yields.Deprotonation of these o-alkenylphenols by the amines occurs in the excited singlet state to give the excited singlet state of the phenolate anion 7 and the ammonium ion.The proton transfer from the ammonium ion to the alkenyl group of 7 generates the zwitterion 8 that allows the nucleophilic addition of the amine at the benzylic cation centre.Similar photoamination of 1-(2-methylpropenyl)-2-naphthol 3 with alkylamines occured to give 1-(1-alkylamino-2-methylpropyl)-2-naphthols 6a-b.
