66175-65-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 66175-65-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,1,7 and 5 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 66175-65:
(7*6)+(6*6)+(5*1)+(4*7)+(3*5)+(2*6)+(1*5)=143
143 % 10 = 3
So 66175-65-3 is a valid CAS Registry Number.
