Check Digit Verification of cas no

The CAS Registry Mumber 63539-52-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,5,3 and 9 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 63539-52:
(7*6)+(6*3)+(5*5)+(4*3)+(3*9)+(2*5)+(1*2)=136
136 % 10 = 6
So 63539-52-6 is a valid CAS Registry Number.
