Check Digit Verification of cas no

The CAS Registry Mumber 389868-23-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,8,9,8,6 and 8 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 389868-23:
(8*3)+(7*8)+(6*9)+(5*8)+(4*6)+(3*8)+(2*2)+(1*3)=229
229 % 10 = 9
So 389868-23-9 is a valid CAS Registry Number.
