406920-23-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 406920-23-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,6,9,2 and 0 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 406920-23:
(8*4)+(7*0)+(6*6)+(5*9)+(4*2)+(3*0)+(2*2)+(1*3)=128
128 % 10 = 8
So 406920-23-8 is a valid CAS Registry Number.
