Check Digit Verification of cas no

The CAS Registry Mumber 944719-28-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,4,7,1 and 9 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 944719-28:
(8*9)+(7*4)+(6*4)+(5*7)+(4*1)+(3*9)+(2*2)+(1*8)=202
202 % 10 = 2
So 944719-28-2 is a valid CAS Registry Number.
