Check Digit Verification of cas no

The CAS Registry Mumber 90133-45-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,1,3 and 3 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 90133-45:
(7*9)+(6*0)+(5*1)+(4*3)+(3*3)+(2*4)+(1*5)=102
102 % 10 = 2
So 90133-45-2 is a valid CAS Registry Number.
