Check Digit Verification of cas no

The CAS Registry Mumber 1697-71-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,9 and 7 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1697-71:
(6*1)+(5*6)+(4*9)+(3*7)+(2*7)+(1*1)=108
108 % 10 = 8
So 1697-71-8 is a valid CAS Registry Number.
