Check Digit Verification of cas no

The CAS Registry Mumber 3938-05-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,3 and 8 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 3938-05:
(6*3)+(5*9)+(4*3)+(3*8)+(2*0)+(1*5)=104
104 % 10 = 4
So 3938-05-4 is a valid CAS Registry Number.
