Check Digit Verification of cas no

The CAS Registry Mumber 139954-70-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,9,5 and 4 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 139954-70:
(8*1)+(7*3)+(6*9)+(5*9)+(4*5)+(3*4)+(2*7)+(1*0)=174
174 % 10 = 4
So 139954-70-4 is a valid CAS Registry Number.
