168431-56-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 168431-56-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,8,4,3 and 1 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 168431-56:
(8*1)+(7*6)+(6*8)+(5*4)+(4*3)+(3*1)+(2*5)+(1*6)=149
149 % 10 = 9
So 168431-56-9 is a valid CAS Registry Number.
