Check Digit Verification of cas no

The CAS Registry Mumber 439694-11-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,9,6,9 and 4 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 439694-11:
(8*4)+(7*3)+(6*9)+(5*6)+(4*9)+(3*4)+(2*1)+(1*1)=188
188 % 10 = 8
So 439694-11-8 is a valid CAS Registry Number.
