Check Digit Verification of cas no

The CAS Registry Mumber 139914-54-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,9,1 and 4 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 139914-54:
(8*1)+(7*3)+(6*9)+(5*9)+(4*1)+(3*4)+(2*5)+(1*4)=158
158 % 10 = 8
So 139914-54-8 is a valid CAS Registry Number.
