222409-84-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 222409-84-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,2,4,0 and 9 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 222409-84:
(8*2)+(7*2)+(6*2)+(5*4)+(4*0)+(3*9)+(2*8)+(1*4)=109
109 % 10 = 9
So 222409-84-9 is a valid CAS Registry Number.
