Check Digit Verification of cas no

The CAS Registry Mumber 219692-69-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,6,9 and 2 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 219692-69:
(8*2)+(7*1)+(6*9)+(5*6)+(4*9)+(3*2)+(2*6)+(1*9)=170
170 % 10 = 0
So 219692-69-0 is a valid CAS Registry Number.
