920874-45-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 920874-45-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,0,8,7 and 4 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 920874-45:
(8*9)+(7*2)+(6*0)+(5*8)+(4*7)+(3*4)+(2*4)+(1*5)=179
179 % 10 = 9
So 920874-45-9 is a valid CAS Registry Number.

, p. 844 - 849 (2008/09/18)
Reaction of 1-alkyl-3-alkylaminopyrrole-2,5-diones with primary arylamine hydrochlorides in methanol or DMSO gives 1-alkyl-3-arylaminopyrrole-2,5-diones which could also be obtained from the reaction of arylaminofumarates with primary aliphatic amines.
