Check Digit Verification of cas no

The CAS Registry Mumber 1197993-07-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,7,9,9 and 3 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1197993-07:
(9*1)+(8*1)+(7*9)+(6*7)+(5*9)+(4*9)+(3*3)+(2*0)+(1*7)=219
219 % 10 = 9
So 1197993-07-9 is a valid CAS Registry Number.
