Check Digit Verification of cas no

The CAS Registry Mumber 4436-05-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,3 and 6 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4436-05:
(6*4)+(5*4)+(4*3)+(3*6)+(2*0)+(1*5)=79
79 % 10 = 9
So 4436-05-9 is a valid CAS Registry Number.
