Check Digit Verification of cas no

The CAS Registry Mumber 68539-16-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,5,3 and 9 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 68539-16:
(7*6)+(6*8)+(5*5)+(4*3)+(3*9)+(2*1)+(1*6)=162
162 % 10 = 2
So 68539-16-2 is a valid CAS Registry Number.
