Check Digit Verification of cas no

The CAS Registry Mumber 1851-38-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,5 and 1 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1851-38:
(6*1)+(5*8)+(4*5)+(3*1)+(2*3)+(1*8)=83
83 % 10 = 3
So 1851-38-3 is a valid CAS Registry Number.
