Check Digit Verification of cas no

The CAS Registry Mumber 63509-20-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,5,0 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 63509-20:
(7*6)+(6*3)+(5*5)+(4*0)+(3*9)+(2*2)+(1*0)=116
116 % 10 = 6
So 63509-20-6 is a valid CAS Registry Number.
