Check Digit Verification of cas no

The CAS Registry Mumber 21520-98-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,5,2 and 0 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 21520-98:
(7*2)+(6*1)+(5*5)+(4*2)+(3*0)+(2*9)+(1*8)=79
79 % 10 = 9
So 21520-98-9 is a valid CAS Registry Number.
