Check Digit Verification of cas no

The CAS Registry Mumber 66384-45-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,3,8 and 4 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 66384-45:
(7*6)+(6*6)+(5*3)+(4*8)+(3*4)+(2*4)+(1*5)=150
150 % 10 = 0
So 66384-45-0 is a valid CAS Registry Number.

A ring-closing metathesis-based approach to the synthesis of (+)-tetrabenazine

Johannes, Manuel,Altmann, Karl-Heinz

supporting information; experimental part, p. 3752 - 3755 (2012/09/07)

A modular stereoselective synthesis of the vesicular monoamine transport inhibitors (+)-tetrabenazine ((+)-1) and (+)-α-dihydrotetrabenazine ((+)-2) has been developed. The approach is based on amine 4 and acid 5 as the key building blocks, which were elaborated into macrolactam 3 by amide coupling and a subsequent highly E-selective RCM reaction. Macrolactam 3 could be converted into tetrabenazine in three known steps.

Application of the ortho-Lithiation-Cyclization Strategy to N-Benzyl- and N-Phenethylamine Derivatives

Lete, Esther,Collado, M. Isabel,Sotomayor, Nuria,Vicente, Teresa,Villa, Maria-Jesus

, p. 1751 - 1758 (2007/10/03)

The ortho-lithiation-cyclization of iodinated N,N-diacylphenethylamines provides a convenient method for the preparation of 2-(2-acetoamidoethyl)acetophenones and 2-(2-benzamidoethyl)benzophenones, which could be easily transformed into dihydroisoquinolines.By contrast, the N-ethylamino, N-acetylamino, and N-trimethylsilylamino moieties studied as ortho-directing groups provide poor assistance to the metalation of N-benzyl- and N-phenyethylamines and the corresponding isoindolone or isoquinolone derivatives are obtained in low yields.
