Check Digit Verification of cas no

The CAS Registry Mumber 90543-02-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,5,4 and 3 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 90543-02:
(7*9)+(6*0)+(5*5)+(4*4)+(3*3)+(2*0)+(1*2)=115
115 % 10 = 5
So 90543-02-5 is a valid CAS Registry Number.
