Check Digit Verification of cas no

The CAS Registry Mumber 187800-99-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,7,8,0 and 0 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 187800-99:
(8*1)+(7*8)+(6*7)+(5*8)+(4*0)+(3*0)+(2*9)+(1*9)=173
173 % 10 = 3
So 187800-99-3 is a valid CAS Registry Number.
