Check Digit Verification of cas no

The CAS Registry Mumber 175444-04-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,5,4,4 and 4 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 175444-04:
(8*1)+(7*7)+(6*5)+(5*4)+(4*4)+(3*4)+(2*0)+(1*4)=139
139 % 10 = 9
So 175444-04-9 is a valid CAS Registry Number.
