Check Digit Verification of cas no

The CAS Registry Mumber 97100-16-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,1,0 and 0 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 97100-16:
(7*9)+(6*7)+(5*1)+(4*0)+(3*0)+(2*1)+(1*6)=118
118 % 10 = 8
So 97100-16-8 is a valid CAS Registry Number.
