Check Digit Verification of cas no

The CAS Registry Mumber 99897-11-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,8,9 and 7 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 99897-11:
(7*9)+(6*9)+(5*8)+(4*9)+(3*7)+(2*1)+(1*1)=217
217 % 10 = 7
So 99897-11-7 is a valid CAS Registry Number.
