Check Digit Verification of cas no

The CAS Registry Mumber 146256-98-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,2,5 and 6 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 146256-98:
(8*1)+(7*4)+(6*6)+(5*2)+(4*5)+(3*6)+(2*9)+(1*8)=146
146 % 10 = 6
So 146256-98-6 is a valid CAS Registry Number.
