1040392-91-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1040392-91-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,0,3,9 and 2 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1040392-91:
(9*1)+(8*0)+(7*4)+(6*0)+(5*3)+(4*9)+(3*2)+(2*9)+(1*1)=113
113 % 10 = 3
So 1040392-91-3 is a valid CAS Registry Number.
