1314033-40-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1314033-40-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,4,0,3 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1314033-40:
(9*1)+(8*3)+(7*1)+(6*4)+(5*0)+(4*3)+(3*3)+(2*4)+(1*0)=93
93 % 10 = 3
So 1314033-40-3 is a valid CAS Registry Number.
