228111-40-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 228111-40-8 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 1 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 228111-40:
(8*2)+(7*2)+(6*8)+(5*1)+(4*1)+(3*1)+(2*4)+(1*0)=98
98 % 10 = 8
So 228111-40-8 is a valid CAS Registry Number.
