Check Digit Verification of cas no

The CAS Registry Mumber 18171-03-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,1,7 and 1 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 18171-03:
(7*1)+(6*8)+(5*1)+(4*7)+(3*1)+(2*0)+(1*3)=94
94 % 10 = 4
So 18171-03-4 is a valid CAS Registry Number.
