84040-12-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 84040-12-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,0,4 and 0 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 84040-12:
(7*8)+(6*4)+(5*0)+(4*4)+(3*0)+(2*1)+(1*2)=100
100 % 10 = 0
So 84040-12-0 is a valid CAS Registry Number.
