Check Digit Verification of cas no

The CAS Registry Mumber 4265-57-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,6 and 5 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4265-57:
(6*4)+(5*2)+(4*6)+(3*5)+(2*5)+(1*7)=90
90 % 10 = 0
So 4265-57-0 is a valid CAS Registry Number.
