Check Digit Verification of cas no
The CAS Registry Mumber 202057-10-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,2,0,5 and 7 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 202057-10:
(8*2)+(7*0)+(6*2)+(5*0)+(4*5)+(3*7)+(2*1)+(1*0)=71
71 % 10 = 1
So 202057-10-1 is a valid CAS Registry Number.

Stereoisomerism in the series of isoindole-based quaternary salts
Gordienko,Tolmachev,Kornilov,Zubatyuk,Shishkin
experimental part, p. 83 - 91 (2011/04/26)
Steric structure of quaternary ammonium salts of the 3-[alkyl(aryl)amino]- 1-[alkyl(aryl)iminio]-1H-isoindole series was studied by 1H NMR spectroscopy and X-ray analysis. The examined salts are characterized by E,E configuration of substituent
