Check Digit Verification of cas no

The CAS Registry Mumber 7132-18-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,1,3 and 2 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 7132-18:
(6*7)+(5*1)+(4*3)+(3*2)+(2*1)+(1*8)=75
75 % 10 = 5
So 7132-18-5 is a valid CAS Registry Number.
