Check Digit Verification of cas no
The CAS Registry Mumber 313957-68-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,3,9,5 and 7 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 313957-68:
(8*3)+(7*1)+(6*3)+(5*9)+(4*5)+(3*7)+(2*6)+(1*8)=155
155 % 10 = 5
So 313957-68-5 is a valid CAS Registry Number.

8-R-5,7-Dinitroquinolines in [3+2] cycloaddition reactions with N-methylazomethine ylide
Bastrakov,Leonov,Starosotnikov,Fedyanin,Shevelev
, (2013)
Novel derivatives of isoindole and dihydroisoindole fused to the pyridine ring were obtained by 1,3-dipolar cycloaddition reactions of N-methylazomethine ylide with substituted 5,7-dinitroquinolines. The substituents in the benzene ring were found to affe
