111252-99-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 111252-99-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,2,5 and 2 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 111252-99:
(8*1)+(7*1)+(6*1)+(5*2)+(4*5)+(3*2)+(2*9)+(1*9)=84
84 % 10 = 4
So 111252-99-4 is a valid CAS Registry Number.
