Check Digit Verification of cas no

The CAS Registry Mumber 116458-75-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,4,5 and 8 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 116458-75:
(8*1)+(7*1)+(6*6)+(5*4)+(4*5)+(3*8)+(2*7)+(1*5)=134
134 % 10 = 4
So 116458-75-4 is a valid CAS Registry Number.
