Check Digit Verification of cas no

The CAS Registry Mumber 944670-19-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,4,6,7 and 0 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 944670-19:
(8*9)+(7*4)+(6*4)+(5*6)+(4*7)+(3*0)+(2*1)+(1*9)=193
193 % 10 = 3
So 944670-19-3 is a valid CAS Registry Number.
