Check Digit Verification of cas no

The CAS Registry Mumber 84441-53-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,4,4 and 1 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 84441-53:
(7*8)+(6*4)+(5*4)+(4*4)+(3*1)+(2*5)+(1*3)=132
132 % 10 = 2
So 84441-53-2 is a valid CAS Registry Number.
