Check Digit Verification of cas no

The CAS Registry Mumber 154385-02-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,4,3,8 and 5 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 154385-02:
(8*1)+(7*5)+(6*4)+(5*3)+(4*8)+(3*5)+(2*0)+(1*2)=131
131 % 10 = 1
So 154385-02-1 is a valid CAS Registry Number.

Reactions of 4-methoxy-3-quinolinyl and 1,4-dihydro-4-oxo-3-quinolinyl sulfides aiming at the synthesis of 4-chloro-3-quinolinyl sulfides [1]

Maslankiewicz,Boryczka

, p. 1623 - 1628 (1993)

The preparation of 1,4-dihydro-4-oxo-3'-alkylthio-3,4'-diquinolinyl sulfides 3 or 1,4-dihydro-4-oxo-3-(alkylthio)quinolines 4 by acid catalysed hydrolysis of 4-methoxy-3'-alkylthio-3,4'-diquinolinyl sulfides 1 or 4- methoxy-3-(alkylthio)-quinolines 2 is described. The reactions of 4-methoxy- 3'-alkylthio-3,4'-diquinolinyl sulfides 1 or 1,4-dihydro-4-oxo-3'-alkylthio- 3,4'-diquinolinyl sulfides 3 with phosphoryl chloride in DMF afforded 4- chloro-3'-alkylthio-3,4'-diquinolinyl sulfides 5. Treatment of the title compounds 1 or 3 with boiling phosphoryl chloride systems: leads to 4- chloro-3-(alkylthio)quinolines 6 and thioquinanthrene but those of alkoxy- or oxo-quinolines 2 or 4 lead to 4-chloro-3-(alkylthio)quinolines 6. The reactions of N-methyl-4(1H)-quinolinones 3n and 4n with phosphoryl chloride directed to 4-chloro-3-(alkylthio)quinolines 6 were studied as well.

1H- and 1-alkyl-1,4-dihydro-4-oxo-3-alkylthioquinolines from 1,4-dihydro-4-oxo-3′-alkylthio-3,4′-diquinolinyl sulfides

Bebenek, Ewa,Chrobak, Elwira,Maslankiewicz, Andrzej

, p. 2065 - 2076 (2007/10/03)

Quinolinones (1) were N-alkylated with alkyl iodides in DMSO or DMF in the presence of potassium methoxide to N-alkyl derivatives (3) (78-98%). One-pot method was elaborated allowing to transform compound (1a) into the mixture of 1-alkyl-3-alkylthio-4(1H)
