111558-41-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 111558-41-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,5,5 and 8 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 111558-41:
(8*1)+(7*1)+(6*1)+(5*5)+(4*5)+(3*8)+(2*4)+(1*1)=99
99 % 10 = 9
So 111558-41-9 is a valid CAS Registry Number.
