Check Digit Verification of cas no

The CAS Registry Mumber 74499-55-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,4,9 and 9 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 74499-55:
(7*7)+(6*4)+(5*4)+(4*9)+(3*9)+(2*5)+(1*5)=171
171 % 10 = 1
So 74499-55-1 is a valid CAS Registry Number.
