Check Digit Verification of cas no

The CAS Registry Mumber 940939-13-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,0,9,3 and 9 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 940939-13:
(8*9)+(7*4)+(6*0)+(5*9)+(4*3)+(3*9)+(2*1)+(1*3)=189
189 % 10 = 9
So 940939-13-9 is a valid CAS Registry Number.
