166274-75-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 166274-75-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,6,2,7 and 4 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 166274-75:
(8*1)+(7*6)+(6*6)+(5*2)+(4*7)+(3*4)+(2*7)+(1*5)=155
155 % 10 = 5
So 166274-75-5 is a valid CAS Registry Number.
