Check Digit Verification of cas no

The CAS Registry Mumber 90448-17-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,4,4 and 8 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 90448-17:
(7*9)+(6*0)+(5*4)+(4*4)+(3*8)+(2*1)+(1*7)=132
132 % 10 = 2
So 90448-17-2 is a valid CAS Registry Number.
