Check Digit Verification of cas no

The CAS Registry Mumber 139757-38-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,7,5 and 7 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 139757-38:
(8*1)+(7*3)+(6*9)+(5*7)+(4*5)+(3*7)+(2*3)+(1*8)=173
173 % 10 = 3
So 139757-38-3 is a valid CAS Registry Number.
