Check Digit Verification of cas no

The CAS Registry Mumber 85993-33-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,9,9 and 3 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 85993-33:
(7*8)+(6*5)+(5*9)+(4*9)+(3*3)+(2*3)+(1*3)=185
185 % 10 = 5
So 85993-33-5 is a valid CAS Registry Number.
