228864-76-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 228864-76-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,8,8,6 and 4 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 228864-76:
(8*2)+(7*2)+(6*8)+(5*8)+(4*6)+(3*4)+(2*7)+(1*6)=174
174 % 10 = 4
So 228864-76-4 is a valid CAS Registry Number.
