Check Digit Verification of cas no

The CAS Registry Mumber 33475-22-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,4,7 and 5 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 33475-22:
(7*3)+(6*3)+(5*4)+(4*7)+(3*5)+(2*2)+(1*2)=108
108 % 10 = 8
So 33475-22-8 is a valid CAS Registry Number.
