228123-21-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 228123-21-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,8,1,2 and 3 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 228123-21:
(8*2)+(7*2)+(6*8)+(5*1)+(4*2)+(3*3)+(2*2)+(1*1)=105
105 % 10 = 5
So 228123-21-5 is a valid CAS Registry Number.
