Check Digit Verification of cas no

The CAS Registry Mumber 188-18-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,8 and 8 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 188-18:
(5*1)+(4*8)+(3*8)+(2*1)+(1*8)=71
71 % 10 = 1
So 188-18-1 is a valid CAS Registry Number.
