Check Digit Verification of cas no

The CAS Registry Mumber 140175-69-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,1,7 and 5 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 140175-69:
(8*1)+(7*4)+(6*0)+(5*1)+(4*7)+(3*5)+(2*6)+(1*9)=105
105 % 10 = 5
So 140175-69-5 is a valid CAS Registry Number.
