Check Digit Verification of cas no

The CAS Registry Mumber 20440-91-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,4,4 and 0 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 20440-91:
(7*2)+(6*0)+(5*4)+(4*4)+(3*0)+(2*9)+(1*1)=69
69 % 10 = 9
So 20440-91-9 is a valid CAS Registry Number.
