224178-20-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 224178-20-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,4,1,7 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 224178-20:
(8*2)+(7*2)+(6*4)+(5*1)+(4*7)+(3*8)+(2*2)+(1*0)=115
115 % 10 = 5
So 224178-20-5 is a valid CAS Registry Number.
