Check Digit Verification of cas no

The CAS Registry Mumber 1256459-97-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,6,4,5 and 9 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1256459-97:
(9*1)+(8*2)+(7*5)+(6*6)+(5*4)+(4*5)+(3*9)+(2*9)+(1*7)=188
188 % 10 = 8
So 1256459-97-8 is a valid CAS Registry Number.
