Check Digit Verification of cas no

The CAS Registry Mumber 1207971-26-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,7,9,7 and 1 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1207971-26:
(9*1)+(8*2)+(7*0)+(6*7)+(5*9)+(4*7)+(3*1)+(2*2)+(1*6)=153
153 % 10 = 3
So 1207971-26-3 is a valid CAS Registry Number.

Scalable and straightforward synthesis of a 2-alkyl-7-arylbenzo-thiophene as a GPR52 agonist via a hemithioindigo derivative

Fukuda, Naohiro,Ikemoto, Tomomi

, p. 3467 - 3472 (2015/11/17)

A simple and efficient procedure has been developed for the synthesis of the GPR52 agonist N-(2-amino-2-oxoethyl)-3-{4-fluoro-2-[3-(trifluoromethyl)benzyl]-1-benzothien-7-yl}benzamide. The benzo thiophene unit was directly constructed by reduction of a hemithioindigo derivative prepared by an intramolecular Friedel-Crafts cyclization of (phenylsulfanyl)acetic acid, followed by dehydrative benzylidene formation.
