Check Digit Verification of cas no

The CAS Registry Mumber 85209-52-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,2,0 and 9 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 85209-52:
(7*8)+(6*5)+(5*2)+(4*0)+(3*9)+(2*5)+(1*2)=135
135 % 10 = 5
So 85209-52-5 is a valid CAS Registry Number.
