Check Digit Verification of cas no

The CAS Registry Mumber 82921-32-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,9,2 and 1 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 82921-32:
(7*8)+(6*2)+(5*9)+(4*2)+(3*1)+(2*3)+(1*2)=132
132 % 10 = 2
So 82921-32-2 is a valid CAS Registry Number.
