Check Digit Verification of cas no

The CAS Registry Mumber 90543-91-2 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, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 90543-91:
(7*9)+(6*0)+(5*5)+(4*4)+(3*3)+(2*9)+(1*1)=132
132 % 10 = 2
So 90543-91-2 is a valid CAS Registry Number.
