4029-42-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4029-42-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,2 and 9 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 4029-42:
(6*4)+(5*0)+(4*2)+(3*9)+(2*4)+(1*2)=69
69 % 10 = 9
So 4029-42-9 is a valid CAS Registry Number.

SYNTHESIS, STRUCTURE, AND CHEMICAL PROPERTIES OF SOME N-(3-CHLORO-2-QUINOXALYL)ARYLSULFONAMIDES
Litvinenko, S. V.,Savich, V. I.,Bobrovnik, L. D.
, p. 340 - 344 (2007/10/02)
We have developed a method for synthesis of N-(3-chloro-2-quinoxalyl)sulfonamides by reaction of 2,3-dichloroquinoxaline with substituted arylsulfonamides.Based on the IR spectra, we have established that in the solid state, the synthesized compounds exis
