Check Digit Verification of cas no

The CAS Registry Mumber 139952-69-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,9,5 and 2 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 139952-69:
(8*1)+(7*3)+(6*9)+(5*9)+(4*5)+(3*2)+(2*6)+(1*9)=175
175 % 10 = 5
So 139952-69-5 is a valid CAS Registry Number.
