Check Digit Verification of cas no

The CAS Registry Mumber 591219-74-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,9,1,2,1 and 9 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 591219-74:
(8*5)+(7*9)+(6*1)+(5*2)+(4*1)+(3*9)+(2*7)+(1*4)=168
168 % 10 = 8
So 591219-74-8 is a valid CAS Registry Number.
