148703-26-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 148703-26-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,8,7,0 and 3 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 148703-26:
(8*1)+(7*4)+(6*8)+(5*7)+(4*0)+(3*3)+(2*2)+(1*6)=138
138 % 10 = 8
So 148703-26-8 is a valid CAS Registry Number.

Pilot scale process development of SL65.0102-10, an N-diazabicyclo[2.2.2]-octylmethyl Benzamide

Lienard, Philippe,Gradoz, Philippe,Greciet, Hélène,Jegham, Samir,Legroux, Didier

, p. 18 - 22 (2017)

The process development and improvements for route selection, adapted to large scale for the pilot-scale preparation of SL65.0102-10, an N-diazabicyclo[2.2.2]-octylmethyl benzamide, a 5-HT3 and 5-HT4 receptor active ligand for the treatment of neurological disorders such as cognition impairment, are described in this article. Notable steps and enhancements are compared to the original route, including the improvement of a chiral epoxide synthesis by shortening the number of chemical steps, the deprotection of a quaternary ammonium salt, and the redesign of the final amidification coupling to avoid chromatography.
