Check Digit Verification of cas no

The CAS Registry Mumber 439136-54-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,9,1,3 and 6 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 439136-54:
(8*4)+(7*3)+(6*9)+(5*1)+(4*3)+(3*6)+(2*5)+(1*4)=156
156 % 10 = 6
So 439136-54-6 is a valid CAS Registry Number.
