224620-33-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 224620-33-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,4,6,2 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 224620-33:
(8*2)+(7*2)+(6*4)+(5*6)+(4*2)+(3*0)+(2*3)+(1*3)=101
101 % 10 = 1
So 224620-33-1 is a valid CAS Registry Number.
