32438-32-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 32438-32-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,2,4,3 and 8 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 32438-32:
(7*3)+(6*2)+(5*4)+(4*3)+(3*8)+(2*3)+(1*2)=97
97 % 10 = 7
So 32438-32-7 is a valid CAS Registry Number.

Synthesis and contractile activity of substituted 1,2,3,4- tetrahydroisoquinolines

Ivanov, Iliyan,Nikolova, Stoyanka,Aladjov, Dimo,Stefanova, Iliyana,Zagorchev, Plamen

experimental part, p. 7019 - 7042 (2011/11/05)

A series of different 1-monosubstituted and 1,1-disubstituted 1,2,3,4-tetrahydroisoquinolines was synthesized in high yields from different ketoamides. We have developed a convenient method for the synthesis of disubstituted derivatives by interaction of

Fragmentation of Enamides Derived from 6,7-Dimethoxy-4-methyl-2H-1,3-benzothiazin and 3,4-Dihydro-6,7-dimethoxy-1-methylisoquinoline

Wang, Jian,Smith, Richard W.,Fodor, Lajos,Maclean, David B.

, p. 830 - 836 (2007/10/02)

The elctron impact mass spectra of several enamides have been examined.The enamides were prepared by reaction of aroyl halides with 6,7-dimethoxy-4-methyl-1,3-benzothiazin, and with 3,4-dihydro-6,7-dimethoxy-1-metylisoquinoline.The fragmentation pathways that have been proposed are supported by ion composition determinations and by mass-analysed ion kinetic energy spectrometry experiments carried out on the molecular ions and major fragment ions.The spectra are characterized by a loss of carbon monoxide from the molecular ion of each compound, a process which is accompanied by migration of the aryl group.
