111149-05-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 111149-05-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,1,4 and 9 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 111149-05:
(8*1)+(7*1)+(6*1)+(5*1)+(4*4)+(3*9)+(2*0)+(1*5)=74
74 % 10 = 4
So 111149-05-4 is a valid CAS Registry Number.
