223128-50-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 223128-50-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,3,1,2 and 8 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 223128-50:
(8*2)+(7*2)+(6*3)+(5*1)+(4*2)+(3*8)+(2*5)+(1*0)=95
95 % 10 = 5
So 223128-50-5 is a valid CAS Registry Number.
