Check Digit Verification of cas no

The CAS Registry Mumber 198219-20-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,8,2,1 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 198219-20:
(8*1)+(7*9)+(6*8)+(5*2)+(4*1)+(3*9)+(2*2)+(1*0)=164
164 % 10 = 4
So 198219-20-4 is a valid CAS Registry Number.
