A derivative of isobenzofuran-1,3-dione with four methyl groups attached to the 4, 5, 6, and 7 positions of the molecule.Check Digit Verification of cas no
The CAS Registry Mumber 4540-48-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,4 and 0 respectively; the second part has 2 digits, 4 and 8 respectively.Calculate Digit Verification of CAS Registry Number 4540-48:
(6*4)+(5*5)+(4*4)+(3*0)+(2*4)+(1*8)=81
81 % 10 = 1
So 4540-48-1 is a valid CAS Registry Number.
