405196-71-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 405196-71-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,5,1,9 and 6 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 405196-71:
(8*4)+(7*0)+(6*5)+(5*1)+(4*9)+(3*6)+(2*7)+(1*1)=136
136 % 10 = 6
So 405196-71-6 is a valid CAS Registry Number.
