Check Digit Verification of cas no

The CAS Registry Mumber 55325-49-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,3,2 and 5 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 55325-49:
(7*5)+(6*5)+(5*3)+(4*2)+(3*5)+(2*4)+(1*9)=120
120 % 10 = 0
So 55325-49-0 is a valid CAS Registry Number.
