Check Digit Verification of cas no

The CAS Registry Mumber 256371-28-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,6,3,7 and 1 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 256371-28:
(8*2)+(7*5)+(6*6)+(5*3)+(4*7)+(3*1)+(2*2)+(1*8)=145
145 % 10 = 5
So 256371-28-5 is a valid CAS Registry Number.
