1131444-93-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1131444-93-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,1,4,4 and 4 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1131444-93:
(9*1)+(8*1)+(7*3)+(6*1)+(5*4)+(4*4)+(3*4)+(2*9)+(1*3)=113
113 % 10 = 3
So 1131444-93-3 is a valid CAS Registry Number.
