Check Digit Verification of cas no

The CAS Registry Mumber 19256-80-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,2,5 and 6 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 19256-80:
(7*1)+(6*9)+(5*2)+(4*5)+(3*6)+(2*8)+(1*0)=125
125 % 10 = 5
So 19256-80-5 is a valid CAS Registry Number.
