112181-49-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 112181-49-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,1,8 and 1 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 112181-49:
(8*1)+(7*1)+(6*2)+(5*1)+(4*8)+(3*1)+(2*4)+(1*9)=84
84 % 10 = 4
So 112181-49-4 is a valid CAS Registry Number.
