Check Digit Verification of cas no

The CAS Registry Mumber 4211-95-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,1 and 1 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4211-95:
(6*4)+(5*2)+(4*1)+(3*1)+(2*9)+(1*5)=64
64 % 10 = 4
So 4211-95-4 is a valid CAS Registry Number.
