Check Digit Verification of cas no

The CAS Registry Mumber 3257-39-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,5 and 7 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 3257-39:
(6*3)+(5*2)+(4*5)+(3*7)+(2*3)+(1*9)=84
84 % 10 = 4
So 3257-39-4 is a valid CAS Registry Number.
