1401031-99-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1401031-99-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,1,0,3 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1401031-99:
(9*1)+(8*4)+(7*0)+(6*1)+(5*0)+(4*3)+(3*1)+(2*9)+(1*9)=89
89 % 10 = 9
So 1401031-99-9 is a valid CAS Registry Number.
