909039-41-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 909039-41-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,9,0,3 and 9 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 909039-41:
(8*9)+(7*0)+(6*9)+(5*0)+(4*3)+(3*9)+(2*4)+(1*1)=174
174 % 10 = 4
So 909039-41-4 is a valid CAS Registry Number.

Synthesis and transformations of substituted 3,3′-diquinolinyl sulfides
Pluta, Krystian
, p. 2457 - 2475 (2007/10/03)
Reactions of the 1,4-dithiin ring opening in 1,4-dithiinodiquinoline 1 with selected oxygen nucleophiles followed by S- and N-alkylation led to sulfides possessing one or two quinolinyl or quinolonyl units. Diquinolinyl sulfides 2 were transformed into qu
