40448-79-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 40448-79-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,4,4 and 8 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 40448-79:
(7*4)+(6*0)+(5*4)+(4*4)+(3*8)+(2*7)+(1*9)=111
111 % 10 = 1
So 40448-79-1 is a valid CAS Registry Number.

, p. 2956 - 2963 (2014/05/20)
The kinetics of the reactions of maleic anhydride, N-methylmaleimide, fumaronitrile, diethyl fumarate, and diethyl maleate with pyridinium and sulfonium ylides were studied in DMSO at 20 C. All of the reactions were found to follow a second-order rate law
