228853-22-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 228853-22-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,8,8,5 and 3 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 228853-22:
(8*2)+(7*2)+(6*8)+(5*8)+(4*5)+(3*3)+(2*2)+(1*2)=153
153 % 10 = 3
So 228853-22-3 is a valid CAS Registry Number.
