Check Digit Verification of cas no

The CAS Registry Mumber 917989-40-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,7,9,8 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 917989-40:
(8*9)+(7*1)+(6*7)+(5*9)+(4*8)+(3*9)+(2*4)+(1*0)=233
233 % 10 = 3
So 917989-40-3 is a valid CAS Registry Number.
