Check Digit Verification of cas no

The CAS Registry Mumber 21753-89-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,7,5 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 21753-89:
(7*2)+(6*1)+(5*7)+(4*5)+(3*3)+(2*8)+(1*9)=109
109 % 10 = 9
So 21753-89-9 is a valid CAS Registry Number.
