The CAS Registry Mumber 944055-46-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,4,0,5 and 5 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 944055-46:
(8*9)+(7*4)+(6*4)+(5*0)+(4*5)+(3*5)+(2*4)+(1*6)=173
173 % 10 = 3
So 944055-46-3 is a valid CAS Registry Number.
