219920-81-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 219920-81-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,9,2 and 0 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 219920-81:
(8*2)+(7*1)+(6*9)+(5*9)+(4*2)+(3*0)+(2*8)+(1*1)=147
147 % 10 = 7
So 219920-81-7 is a valid CAS Registry Number.

Described is the efficient synthesis of an easy to manipulate and utilize, soluble tartrate salt of a potent, reversible butyrylcholinesterase inhibitor, (?)-(3aS)-3a-methyl-1,2,3,3a,8,8a-hexahydropyrrolo-[2,3-b]indol-5-yl N—4′-isopropylphenylcarbamate (“

A practical conversion of natural physostigmine into the potent butyrylcholinesterase inhibitor N1,N8-bisnorcymserine

Zhu, Xiaoxiang,Greig, Nigel H.,Holloway, Harold W.,Whittaker, Noel F.,Brossi, Arnold,Yu, Qian-Sheng

, p. 4861 - 4864 (2007/10/03)

A rapid novel synthetic route to the potent reversible butyrylcholinesterase inhibitor (-)-N1,N8-bisnorcymserine (1) is reported from physostigmine (2) in a 20% total yield. Details on the formation of the imino-quinone 6 obtained in the oxidation of N1-benzylnoresermethole (4) and its conversion into N1-bisnoreseroline (7) are given. As expected, the product of this synthesis, (1), had identical biological activity to the same agent produced by total synthesis. (C) 2000 Elsevier Science Ltd.
