3611-33-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3611-33-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,6,1 and 1 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 3611-33:
(6*3)+(5*6)+(4*1)+(3*1)+(2*3)+(1*3)=64
64 % 10 = 4
So 3611-33-4 is a valid CAS Registry Number.

Enantioselective Oxidative Aerobic Dealkylation of N-Ethyl Benzylisoquinolines by Employing the Berberine Bridge Enzyme

Gandomkar, Somayyeh,Fischereder, Eva-Maria,Schrittwieser, Joerg H.,Wallner, Silvia,Habibi, Zohreh,Macheroux, Peter,Kroutil, Wolfgang

, p. 15051 - 15054 (2016/01/25)

N-Dealkylation methods are well described for organic chemistry and the reaction is known in nature and drug metabolism; however, to our knowledge, enantioselective N-dealkylation has not been yet reported. In this study, exclusively the (S)-enantiomers o

A general methodology for the enantioselective synthesis of 1-substituted tetrahydroisoquinoline alkaloids

Amat, Mercedes,Elias, Viviane,Llor, Nuria,Subrizi, Fabiana,Molins, Elies,Bosch, Joan

experimental part, p. 4017 - 4026 (2010/10/02)

Starting from tricyclic lactam 2, which is easily accessible by cyclocondensation of δ-oxoester 1 with (R)-phenylglycinol, a three-step synthetic route to enantiopure 1-substituted tetrahydroisoquinolines, including 1-alkyl-, 1-aryl-, and 1-benzyltetrahydroisoquinoline alkaloids, as well as the tricyclic alkaloid (-)-crispine A, has been developed. The key step is a stereoselective α-amidoalkylation reaction using the appropriate Grignard reagent.

Enantioselective synthesis of (R)-(+)- and (S)-(-)-higenamine and their analogues with effects on platelet aggregation and experimental animal model of disseminated intravascular coagulation

Pyo, Mi Kyung,Lee, Duck-Hyung,Kim, Doo-Hyun,Lee, Ji-Hye,Moon, Jong-Cheon,Chang, Ki Churl,Yun-Choi, Hye Sook

body text, p. 4110 - 4114 (2009/05/26)

Optically active tetrahydroisoquinoline alkaloids, (R)-(+)-higenamine (1R) and (S)-(-)-higenamine (1 S), and their optically active 1-naphthylmethyl analogues (2 and 3), were synthesized by enantioselective hydrogenation of the corresponding dihydroisoqui
