Check Digit Verification of cas no

The CAS Registry Mumber 50392-39-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,3,9 and 2 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 50392-39:
(7*5)+(6*0)+(5*3)+(4*9)+(3*2)+(2*3)+(1*9)=107
107 % 10 = 7
So 50392-39-7 is a valid CAS Registry Number.
