433289-59-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 433289-59-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,3,2,8 and 9 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 433289-59:
(8*4)+(7*3)+(6*3)+(5*2)+(4*8)+(3*9)+(2*5)+(1*9)=159
159 % 10 = 9
So 433289-59-9 is a valid CAS Registry Number.
