Check Digit Verification of cas no

The CAS Registry Mumber 4422-97-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,2 and 2 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4422-97:
(6*4)+(5*4)+(4*2)+(3*2)+(2*9)+(1*7)=83
83 % 10 = 3
So 4422-97-3 is a valid CAS Registry Number.
