166093-45-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 166093-45-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,6,0,9 and 3 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 166093-45:
(8*1)+(7*6)+(6*6)+(5*0)+(4*9)+(3*3)+(2*4)+(1*5)=144
144 % 10 = 4
So 166093-45-4 is a valid CAS Registry Number.
