Check Digit Verification of cas no

The CAS Registry Mumber 22332-89-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,3,3 and 2 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 22332-89:
(7*2)+(6*2)+(5*3)+(4*3)+(3*2)+(2*8)+(1*9)=84
84 % 10 = 4
So 22332-89-4 is a valid CAS Registry Number.
