Check Digit Verification of cas no

The CAS Registry Mumber 75072-52-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,0,7 and 2 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 75072-52:
(7*7)+(6*5)+(5*0)+(4*7)+(3*2)+(2*5)+(1*2)=125
125 % 10 = 5
So 75072-52-5 is a valid CAS Registry Number.
