Check Digit Verification of cas no

The CAS Registry Mumber 121620-03-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,6,2 and 0 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 121620-03:
(8*1)+(7*2)+(6*1)+(5*6)+(4*2)+(3*0)+(2*0)+(1*3)=69
69 % 10 = 9
So 121620-03-9 is a valid CAS Registry Number.
