Check Digit Verification of cas no

The CAS Registry Mumber 139697-20-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,6,9 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 139697-20:
(8*1)+(7*3)+(6*9)+(5*6)+(4*9)+(3*7)+(2*2)+(1*0)=174
174 % 10 = 4
So 139697-20-4 is a valid CAS Registry Number.
