Check Digit Verification of cas no

The CAS Registry Mumber 77971-16-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,9,7 and 1 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 77971-16:
(7*7)+(6*7)+(5*9)+(4*7)+(3*1)+(2*1)+(1*6)=175
175 % 10 = 5
So 77971-16-5 is a valid CAS Registry Number.
