Check Digit Verification of cas no

The CAS Registry Mumber 98449-73-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,4,4 and 9 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 98449-73:
(7*9)+(6*8)+(5*4)+(4*4)+(3*9)+(2*7)+(1*3)=191
191 % 10 = 1
So 98449-73-1 is a valid CAS Registry Number.
