146664-23-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 146664-23-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,6,6 and 4 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 146664-23:
(8*1)+(7*4)+(6*6)+(5*6)+(4*6)+(3*4)+(2*2)+(1*3)=145
145 % 10 = 5
So 146664-23-5 is a valid CAS Registry Number.
