Check Digit Verification of cas no

The CAS Registry Mumber 20728-91-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,7,2 and 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 20728-91:
(7*2)+(6*0)+(5*7)+(4*2)+(3*8)+(2*9)+(1*1)=100
100 % 10 = 0
So 20728-91-0 is a valid CAS Registry Number.
