Check Digit Verification of cas no

The CAS Registry Mumber 5305-91-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,0 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 5305-91:
(6*5)+(5*3)+(4*0)+(3*5)+(2*9)+(1*1)=79
79 % 10 = 9
So 5305-91-9 is a valid CAS Registry Number.
