The CAS Registry Mumber 129453-38-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,4,5 and 3 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 129453-38:
(8*1)+(7*2)+(6*9)+(5*4)+(4*5)+(3*3)+(2*3)+(1*8)=139
139 % 10 = 9
So 129453-38-9 is a valid CAS Registry Number.
