Check Digit Verification of cas no

The CAS Registry Mumber 85694-28-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,6,9 and 4 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 85694-28:
(7*8)+(6*5)+(5*6)+(4*9)+(3*4)+(2*2)+(1*8)=176
176 % 10 = 6
So 85694-28-6 is a valid CAS Registry Number.
