Check Digit Verification of cas no

The CAS Registry Mumber 125179-56-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,1,7 and 9 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 125179-56:
(8*1)+(7*2)+(6*5)+(5*1)+(4*7)+(3*9)+(2*5)+(1*6)=128
128 % 10 = 8
So 125179-56-8 is a valid CAS Registry Number.
