1394002-81-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1394002-81-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,4,0,0 and 2 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1394002-81:
(9*1)+(8*3)+(7*9)+(6*4)+(5*0)+(4*0)+(3*2)+(2*8)+(1*1)=143
143 % 10 = 3
So 1394002-81-3 is a valid CAS Registry Number.
