41403-35-4 Usage
Uses
2,5-Furandione-3,4-13C2 is used in the study of chemistry of synthetic high polymers such as the 13C NMR study of the mechanism of maleic anhydride grafting onto polyolefins and maleated polyolefins structures.2,5-Furandione-3,4-13C2 is also the labeled version of maleic anhydride, M124400.
Check Digit Verification of cas no
The CAS Registry Mumber 41403-35-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,4,0 and 3 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 41403-35:
(7*4)+(6*1)+(5*4)+(4*0)+(3*3)+(2*3)+(1*5)=74
74 % 10 = 4
So 41403-35-4 is a valid CAS Registry Number.
