Check Digit Verification of cas no

The CAS Registry Mumber 99300-52-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,3,0 and 0 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 99300-52:
(7*9)+(6*9)+(5*3)+(4*0)+(3*0)+(2*5)+(1*2)=144
144 % 10 = 4
So 99300-52-4 is a valid CAS Registry Number.
