Check Digit Verification of cas no

The CAS Registry Mumber 895-04-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,9 and 5 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 895-04:
(5*8)+(4*9)+(3*5)+(2*0)+(1*4)=95
95 % 10 = 5
So 895-04-5 is a valid CAS Registry Number.
