The CAS Registry Mumber 129109-46-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,1,0 and 9 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 129109-46:
(8*1)+(7*2)+(6*9)+(5*1)+(4*0)+(3*9)+(2*4)+(1*6)=122
122 % 10 = 2
So 129109-46-2 is a valid CAS Registry Number.
