258267-14-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 258267-14-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,8,2,6 and 7 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 258267-14:
(8*2)+(7*5)+(6*8)+(5*2)+(4*6)+(3*7)+(2*1)+(1*4)=160
160 % 10 = 0
So 258267-14-0 is a valid CAS Registry Number.

4,4-Dimethyl-4,5-dihydro-1,2-dithiolo-[3,4-c]quinoline-1-thiones in 1,3-dipolar cycloaddition reactions with acetylenic dipolarophiles

Shikhaliev,Medvedeva,Ermolova,Shatalov

, p. 587 - 591 (2007/10/03)

The behavior of 4,4-dimethyl-4,5-dihydro-1,2-dithiolo[3,4-c]quinoline-1-thiones in the 1,3-dipolar cycloaddition reaction with acetylenic dipolarophiles has been studied. The rate of cycloaddition is reduced along with the decrease of electron-deficiency of the triple bond. Substituted 4-(1′,3′-dithiol-2′-ylidene)-1,2-dihydroquinoline-3-thiones were shown to be the reaction products. On using a twofold excess of acetylenedicarboxylic acid dimethyl ester, adducts of composition 1 : 2 were formed which occured to be substituted 1′,3′-dithiole-2′-spiro-1-(5,6-dihydrothiino[2,3-c]quinolines) . 1999 KluwerAcademic/Plenum Publishers.
