Check Digit Verification of cas no

The CAS Registry Mumber 658040-57-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,5,8,0,4 and 0 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 658040-57:
(8*6)+(7*5)+(6*8)+(5*0)+(4*4)+(3*0)+(2*5)+(1*7)=164
164 % 10 = 4
So 658040-57-4 is a valid CAS Registry Number.
