Check Digit Verification of cas no

The CAS Registry Mumber 691869-51-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,9,1,8,6 and 9 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 691869-51:
(8*6)+(7*9)+(6*1)+(5*8)+(4*6)+(3*9)+(2*5)+(1*1)=219
219 % 10 = 9
So 691869-51-9 is a valid CAS Registry Number.
