121089-86-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 121089-86-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,0,8 and 9 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 121089-86:
(8*1)+(7*2)+(6*1)+(5*0)+(4*8)+(3*9)+(2*8)+(1*6)=109
109 % 10 = 9
So 121089-86-9 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

STUDIES ON FRIEDEL-CRAFTS ACYLATION OF N-ACETYLHOMOVERATRYLAMINE AND PREPARATION OF 1-SUBSTITUTED 3,4-DIHYDRO-6,7-DIMETHOXYISOQUINOLINES

Orito, Kazuhiko,Matsuzaki, Tsutomu,Suginome, Hiroshi,Rodrigo, Russel

, p. 2403 - 2412 (2007/10/02)

Friedel-Crafts acylation of N-acetylhomoveratrylamine in a molar ratio of 1:2:3 of 1, AlCl3 and the appropriate acid chloride using nitrobenzene as solvent gave the corresponding 2-acyl derivatives 2a-j in good yields.Subsequent treatment of 2 in boiling
