Check Digit Verification of cas no

The CAS Registry Mumber 39538-57-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,5,3 and 8 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 39538-57:
(7*3)+(6*9)+(5*5)+(4*3)+(3*8)+(2*5)+(1*7)=153
153 % 10 = 3
So 39538-57-3 is a valid CAS Registry Number.
