1140448-08-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1140448-08-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,4,0,4,4 and 8 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1140448-08:
(9*1)+(8*1)+(7*4)+(6*0)+(5*4)+(4*4)+(3*8)+(2*0)+(1*8)=113
113 % 10 = 3
So 1140448-08-3 is a valid CAS Registry Number.
