Check Digit Verification of cas no

The CAS Registry Mumber 219993-02-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,9,9 and 3 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 219993-02:
(8*2)+(7*1)+(6*9)+(5*9)+(4*9)+(3*3)+(2*0)+(1*2)=169
169 % 10 = 9
So 219993-02-9 is a valid CAS Registry Number.
