220247-23-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 220247-23-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,2,4 and 7 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 220247-23:
(8*2)+(7*2)+(6*0)+(5*2)+(4*4)+(3*7)+(2*2)+(1*3)=84
84 % 10 = 4
So 220247-23-4 is a valid CAS Registry Number.
