Check Digit Verification of cas no

The CAS Registry Mumber 1644-55-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,4 and 4 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1644-55:
(6*1)+(5*6)+(4*4)+(3*4)+(2*5)+(1*5)=79
79 % 10 = 9
So 1644-55-9 is a valid CAS Registry Number.
