Check Digit Verification of cas no

The CAS Registry Mumber 16256-31-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,2,5 and 6 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 16256-31:
(7*1)+(6*6)+(5*2)+(4*5)+(3*6)+(2*3)+(1*1)=98
98 % 10 = 8
So 16256-31-8 is a valid CAS Registry Number.
