331459-99-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 331459-99-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,1,4,5 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 331459-99:
(8*3)+(7*3)+(6*1)+(5*4)+(4*5)+(3*9)+(2*9)+(1*9)=145
145 % 10 = 5
So 331459-99-5 is a valid CAS Registry Number.
