84331-39-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 84331-39-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,3,3 and 1 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 84331-39:
(7*8)+(6*4)+(5*3)+(4*3)+(3*1)+(2*3)+(1*9)=125
125 % 10 = 5
So 84331-39-5 is a valid CAS Registry Number.
