Check Digit Verification of cas no

The CAS Registry Mumber 81197-47-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,1,9 and 7 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 81197-47:
(7*8)+(6*1)+(5*1)+(4*9)+(3*7)+(2*4)+(1*7)=139
139 % 10 = 9
So 81197-47-9 is a valid CAS Registry Number.
