Check Digit Verification of cas no

The CAS Registry Mumber 99901-70-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,9,0 and 1 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 99901-70:
(7*9)+(6*9)+(5*9)+(4*0)+(3*1)+(2*7)+(1*0)=179
179 % 10 = 9
So 99901-70-9 is a valid CAS Registry Number.
