220184-55-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 220184-55-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,1,8 and 4 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 220184-55:
(8*2)+(7*2)+(6*0)+(5*1)+(4*8)+(3*4)+(2*5)+(1*5)=94
94 % 10 = 4
So 220184-55-4 is a valid CAS Registry Number.
