Check Digit Verification of cas no

The CAS Registry Mumber 64110-84-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,1,1 and 0 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 64110-84:
(7*6)+(6*4)+(5*1)+(4*1)+(3*0)+(2*8)+(1*4)=95
95 % 10 = 5
So 64110-84-5 is a valid CAS Registry Number.
