111254-33-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 111254-33-2 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 4 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 111254-33:
(8*1)+(7*1)+(6*1)+(5*2)+(4*5)+(3*4)+(2*3)+(1*3)=72
72 % 10 = 2
So 111254-33-2 is a valid CAS Registry Number.
