111751-72-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 111751-72-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,7,5 and 1 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 111751-72:
(8*1)+(7*1)+(6*1)+(5*7)+(4*5)+(3*1)+(2*7)+(1*2)=95
95 % 10 = 5
So 111751-72-5 is a valid CAS Registry Number.
