Check Digit Verification of cas no

The CAS Registry Mumber 550-52-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,5 and 0 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 550-52:
(5*5)+(4*5)+(3*0)+(2*5)+(1*2)=57
57 % 10 = 7
So 550-52-7 is a valid CAS Registry Number.
