1542203-33-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1542203-33-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,4,2,2,0 and 3 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1542203-33:
(9*1)+(8*5)+(7*4)+(6*2)+(5*2)+(4*0)+(3*3)+(2*3)+(1*3)=117
117 % 10 = 7
So 1542203-33-7 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
, p. 1052 - 1059 (2014/03/21)
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
