Check Digit Verification of cas no

The CAS Registry Mumber 189219-04-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,2,1 and 9 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 189219-04:
(8*1)+(7*8)+(6*9)+(5*2)+(4*1)+(3*9)+(2*0)+(1*4)=163
163 % 10 = 3
So 189219-04-3 is a valid CAS Registry Number.
