111199-20-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 111199-20-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,1,9 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 111199-20:
(8*1)+(7*1)+(6*1)+(5*1)+(4*9)+(3*9)+(2*2)+(1*0)=93
93 % 10 = 3
So 111199-20-3 is a valid CAS Registry Number.
