Check Digit Verification of cas no

The CAS Registry Mumber 69981-60-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,9,8 and 1 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 69981-60:
(7*6)+(6*9)+(5*9)+(4*8)+(3*1)+(2*6)+(1*0)=188
188 % 10 = 8
So 69981-60-8 is a valid CAS Registry Number.
