Check Digit Verification of cas no

The CAS Registry Mumber 4692-38-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,9 and 2 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4692-38:
(6*4)+(5*6)+(4*9)+(3*2)+(2*3)+(1*8)=110
110 % 10 = 0
So 4692-38-0 is a valid CAS Registry Number.
