Check Digit Verification of cas no

The CAS Registry Mumber 99438-52-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,4,3 and 8 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 99438-52:
(7*9)+(6*9)+(5*4)+(4*3)+(3*8)+(2*5)+(1*2)=185
185 % 10 = 5
So 99438-52-5 is a valid CAS Registry Number.
