Check Digit Verification of cas no

The CAS Registry Mumber 944472-98-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,4,4,7 and 2 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 944472-98:
(8*9)+(7*4)+(6*4)+(5*4)+(4*7)+(3*2)+(2*9)+(1*8)=204
204 % 10 = 4
So 944472-98-4 is a valid CAS Registry Number.
