Check Digit Verification of cas no

The CAS Registry Mumber 219518-59-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,5,1 and 8 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 219518-59:
(8*2)+(7*1)+(6*9)+(5*5)+(4*1)+(3*8)+(2*5)+(1*9)=149
149 % 10 = 9
So 219518-59-9 is a valid CAS Registry Number.
