67666-75-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 67666-75-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,6,6 and 6 respectively; the second part has 2 digits, 7 and 5 respectively.Calculate Digit Verification of CAS Registry Number 67666-75:
(7*6)+(6*7)+(5*6)+(4*6)+(3*6)+(2*7)+(1*5)=175
175 % 10 = 5
So 67666-75-5 is a valid CAS Registry Number.
