Check Digit Verification of cas no

The CAS Registry Mumber 843673-30-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,3,6,7 and 3 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 843673-30:
(8*8)+(7*4)+(6*3)+(5*6)+(4*7)+(3*3)+(2*3)+(1*0)=183
183 % 10 = 3
So 843673-30-3 is a valid CAS Registry Number.
