Check Digit Verification of cas no

The CAS Registry Mumber 81256-07-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,2,5 and 6 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 81256-07:
(7*8)+(6*1)+(5*2)+(4*5)+(3*6)+(2*0)+(1*7)=117
117 % 10 = 7
So 81256-07-7 is a valid CAS Registry Number.
