146431-40-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 146431-40-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,4,3 and 1 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 146431-40:
(8*1)+(7*4)+(6*6)+(5*4)+(4*3)+(3*1)+(2*4)+(1*0)=115
115 % 10 = 5
So 146431-40-5 is a valid CAS Registry Number.
