Check Digit Verification of cas no

The CAS Registry Mumber 4380-12-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,8 and 0 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 4380-12:
(6*4)+(5*3)+(4*8)+(3*0)+(2*1)+(1*2)=75
75 % 10 = 5
So 4380-12-5 is a valid CAS Registry Number.
