Check Digit Verification of cas no

The CAS Registry Mumber 97911-71-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,9,1 and 1 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 97911-71:
(7*9)+(6*7)+(5*9)+(4*1)+(3*1)+(2*7)+(1*1)=172
172 % 10 = 2
So 97911-71-2 is a valid CAS Registry Number.
