Check Digit Verification of cas no

The CAS Registry Mumber 2257-39-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,5 and 7 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2257-39:
(6*2)+(5*2)+(4*5)+(3*7)+(2*3)+(1*9)=78
78 % 10 = 8
So 2257-39-8 is a valid CAS Registry Number.
