Check Digit Verification of cas no

The CAS Registry Mumber 181256-82-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,1,2,5 and 6 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 181256-82:
(8*1)+(7*8)+(6*1)+(5*2)+(4*5)+(3*6)+(2*8)+(1*2)=136
136 % 10 = 6
So 181256-82-6 is a valid CAS Registry Number.
