Check Digit Verification of cas no

The CAS Registry Mumber 98546-54-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,5,4 and 6 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 98546-54:
(7*9)+(6*8)+(5*5)+(4*4)+(3*6)+(2*5)+(1*4)=184
184 % 10 = 4
So 98546-54-4 is a valid CAS Registry Number.
