The CAS Registry Mumber 53982-53-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,9,8 and 2 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 53982-53:
(7*5)+(6*3)+(5*9)+(4*8)+(3*2)+(2*5)+(1*3)=149
149 % 10 = 9
So 53982-53-9 is a valid CAS Registry Number.
