Check Digit Verification of cas no

The CAS Registry Mumber 288-67-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,8 and 8 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 288-67:
(5*2)+(4*8)+(3*8)+(2*6)+(1*7)=85
85 % 10 = 5
So 288-67-5 is a valid CAS Registry Number.
