Check Digit Verification of cas no

The CAS Registry Mumber 6256-44-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,5 and 6 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 6256-44:
(6*6)+(5*2)+(4*5)+(3*6)+(2*4)+(1*4)=96
96 % 10 = 6
So 6256-44-6 is a valid CAS Registry Number.
