Check Digit Verification of cas no

The CAS Registry Mumber 257628-95-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,7,6,2 and 8 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 257628-95:
(8*2)+(7*5)+(6*7)+(5*6)+(4*2)+(3*8)+(2*9)+(1*5)=178
178 % 10 = 8
So 257628-95-8 is a valid CAS Registry Number.
