Check Digit Verification of cas no

The CAS Registry Mumber 71722-05-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,7,2 and 2 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 71722-05:
(7*7)+(6*1)+(5*7)+(4*2)+(3*2)+(2*0)+(1*5)=109
109 % 10 = 9
So 71722-05-9 is a valid CAS Registry Number.
