84022-44-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 84022-44-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,0,2 and 2 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 84022-44:
(7*8)+(6*4)+(5*0)+(4*2)+(3*2)+(2*4)+(1*4)=106
106 % 10 = 6
So 84022-44-6 is a valid CAS Registry Number.
