111493-23-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 111493-23-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,4,9 and 3 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 111493-23:
(8*1)+(7*1)+(6*1)+(5*4)+(4*9)+(3*3)+(2*2)+(1*3)=93
93 % 10 = 3
So 111493-23-3 is a valid CAS Registry Number.
