Check Digit Verification of cas no

The CAS Registry Mumber 257640-86-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,7,6,4 and 0 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 257640-86:
(8*2)+(7*5)+(6*7)+(5*6)+(4*4)+(3*0)+(2*8)+(1*6)=161
161 % 10 = 1
So 257640-86-1 is a valid CAS Registry Number.
