Check Digit Verification of cas no

The CAS Registry Mumber 1192173-50-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,2,1,7 and 3 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1192173-50:
(9*1)+(8*1)+(7*9)+(6*2)+(5*1)+(4*7)+(3*3)+(2*5)+(1*0)=144
144 % 10 = 4
So 1192173-50-4 is a valid CAS Registry Number.
