Check Digit Verification of cas no

The CAS Registry Mumber 189-73-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,8 and 9 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 189-73:
(5*1)+(4*8)+(3*9)+(2*7)+(1*3)=81
81 % 10 = 1
So 189-73-1 is a valid CAS Registry Number.
