104331-99-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 104331-99-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,3,3 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 104331-99:
(8*1)+(7*0)+(6*4)+(5*3)+(4*3)+(3*1)+(2*9)+(1*9)=89
89 % 10 = 9
So 104331-99-9 is a valid CAS Registry Number.
