Check Digit Verification of cas no

The CAS Registry Mumber 3902-54-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,0 and 2 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 3902-54:
(6*3)+(5*9)+(4*0)+(3*2)+(2*5)+(1*4)=83
83 % 10 = 3
So 3902-54-3 is a valid CAS Registry Number.
