Check Digit Verification of cas no

The CAS Registry Mumber 7544-00-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,5,4 and 4 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 7544-00:
(6*7)+(5*5)+(4*4)+(3*4)+(2*0)+(1*0)=95
95 % 10 = 5
So 7544-00-5 is a valid CAS Registry Number.
