Check Digit Verification of cas no

The CAS Registry Mumber 13473-26-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,4,7 and 3 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 13473-26:
(7*1)+(6*3)+(5*4)+(4*7)+(3*3)+(2*2)+(1*6)=92
92 % 10 = 2
So 13473-26-2 is a valid CAS Registry Number.
