Check Digit Verification of cas no

The CAS Registry Mumber 200335-51-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,0,3,3 and 5 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 200335-51:
(8*2)+(7*0)+(6*0)+(5*3)+(4*3)+(3*5)+(2*5)+(1*1)=69
69 % 10 = 9
So 200335-51-9 is a valid CAS Registry Number.
