Check Digit Verification of cas no

The CAS Registry Mumber 99305-36-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,3,0 and 5 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 99305-36:
(7*9)+(6*9)+(5*3)+(4*0)+(3*5)+(2*3)+(1*6)=159
159 % 10 = 9
So 99305-36-9 is a valid CAS Registry Number.
