Check Digit Verification of cas no

The CAS Registry Mumber 55439-34-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,4,3 and 9 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 55439-34:
(7*5)+(6*5)+(5*4)+(4*3)+(3*9)+(2*3)+(1*4)=134
134 % 10 = 4
