Check Digit Verification of cas no

The CAS Registry Mumber 681216-68-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,1,2,1 and 6 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 681216-68:
(8*6)+(7*8)+(6*1)+(5*2)+(4*1)+(3*6)+(2*6)+(1*8)=162
162 % 10 = 2
So 681216-68-2 is a valid CAS Registry Number.
