1431-00-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1431-00-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,3 and 1 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1431-00:
(6*1)+(5*4)+(4*3)+(3*1)+(2*0)+(1*0)=41
41 % 10 = 1
So 1431-00-1 is a valid CAS Registry Number.
