Check Digit Verification of cas no

The CAS Registry Mumber 183868-03-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,3,8,6 and 8 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 183868-03:
(8*1)+(7*8)+(6*3)+(5*8)+(4*6)+(3*8)+(2*0)+(1*3)=173
173 % 10 = 3
So 183868-03-3 is a valid CAS Registry Number.
