228113-64-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 228113-64-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,8,1,1 and 3 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 228113-64:
(8*2)+(7*2)+(6*8)+(5*1)+(4*1)+(3*3)+(2*6)+(1*4)=112
112 % 10 = 2
So 228113-64-2 is a valid CAS Registry Number.
