1403889-71-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1403889-71-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,3,8,8 and 9 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1403889-71:
(9*1)+(8*4)+(7*0)+(6*3)+(5*8)+(4*8)+(3*9)+(2*7)+(1*1)=173
173 % 10 = 3
So 1403889-71-3 is a valid CAS Registry Number.
