Check Digit Verification of cas no

The CAS Registry Mumber 1174522-50-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,4,5,2 and 2 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1174522-50:
(9*1)+(8*1)+(7*7)+(6*4)+(5*5)+(4*2)+(3*2)+(2*5)+(1*0)=139
139 % 10 = 9
So 1174522-50-9 is a valid CAS Registry Number.
