Check Digit Verification of cas no

The CAS Registry Mumber 880384-20-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,0,3,8 and 4 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 880384-20:
(8*8)+(7*8)+(6*0)+(5*3)+(4*8)+(3*4)+(2*2)+(1*0)=183
183 % 10 = 3
So 880384-20-3 is a valid CAS Registry Number.
