The CAS Registry Mumber 129841-50-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,8,4 and 1 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 129841-50:
(8*1)+(7*2)+(6*9)+(5*8)+(4*4)+(3*1)+(2*5)+(1*0)=145
145 % 10 = 5
So 129841-50-5 is a valid CAS Registry Number.
