The CAS Registry Mumber 129529-33-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,5,2 and 9 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 129529-33:
(8*1)+(7*2)+(6*9)+(5*5)+(4*2)+(3*9)+(2*3)+(1*3)=145
145 % 10 = 5
So 129529-33-5 is a valid CAS Registry Number.
