Check Digit Verification of cas no

The CAS Registry Mumber 259198-96-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,9,1,9 and 8 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 259198-96:
(8*2)+(7*5)+(6*9)+(5*1)+(4*9)+(3*8)+(2*9)+(1*6)=194
194 % 10 = 4
So 259198-96-4 is a valid CAS Registry Number.
