Check Digit Verification of cas no

The CAS Registry Mumber 256398-61-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,6,3,9 and 8 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 256398-61:
(8*2)+(7*5)+(6*6)+(5*3)+(4*9)+(3*8)+(2*6)+(1*1)=175
175 % 10 = 5
So 256398-61-5 is a valid CAS Registry Number.
