The CAS Registry Mumber 543720-25-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,4,3,7,2 and 0 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 543720-25:
(8*5)+(7*4)+(6*3)+(5*7)+(4*2)+(3*0)+(2*2)+(1*5)=138
138 % 10 = 8
So 543720-25-8 is a valid CAS Registry Number.
