Check Digit Verification of cas no

The CAS Registry Mumber 1346240-85-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,6,2,4 and 0 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1346240-85:
(9*1)+(8*3)+(7*4)+(6*6)+(5*2)+(4*4)+(3*0)+(2*8)+(1*5)=144
144 % 10 = 4
