111160-45-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 111160-45-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,1,6 and 0 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 111160-45:
(8*1)+(7*1)+(6*1)+(5*1)+(4*6)+(3*0)+(2*4)+(1*5)=63
63 % 10 = 3
So 111160-45-3 is a valid CAS Registry Number.
