Check Digit Verification of cas no

The CAS Registry Mumber 229489-92-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,9,4,8 and 9 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 229489-92:
(8*2)+(7*2)+(6*9)+(5*4)+(4*8)+(3*9)+(2*9)+(1*2)=183
183 % 10 = 3
So 229489-92-3 is a valid CAS Registry Number.
