Check Digit Verification of cas no

The CAS Registry Mumber 197247-83-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,2,4 and 7 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 197247-83:
(8*1)+(7*9)+(6*7)+(5*2)+(4*4)+(3*7)+(2*8)+(1*3)=179
179 % 10 = 9
So 197247-83-9 is a valid CAS Registry Number.
