Check Digit Verification of cas no

The CAS Registry Mumber 3445-06-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,4 and 5 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 3445-06:
(6*3)+(5*4)+(4*4)+(3*5)+(2*0)+(1*6)=75
75 % 10 = 5
So 3445-06-5 is a valid CAS Registry Number.
