Check Digit Verification of cas no

The CAS Registry Mumber 1197344-04-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,7,3,4 and 4 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1197344-04:
(9*1)+(8*1)+(7*9)+(6*7)+(5*3)+(4*4)+(3*4)+(2*0)+(1*4)=169
169 % 10 = 9
So 1197344-04-9 is a valid CAS Registry Number.
