Check Digit Verification of cas no

The CAS Registry Mumber 5351-51-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,5 and 1 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 5351-51:
(6*5)+(5*3)+(4*5)+(3*1)+(2*5)+(1*1)=79
79 % 10 = 9
So 5351-51-9 is a valid CAS Registry Number.
