Check Digit Verification of cas no

The CAS Registry Mumber 139306-23-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,3,0 and 6 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 139306-23:
(8*1)+(7*3)+(6*9)+(5*3)+(4*0)+(3*6)+(2*2)+(1*3)=123
123 % 10 = 3
So 139306-23-3 is a valid CAS Registry Number.
