3665-75-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 3665-75-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,6,6 and 5 respectively; the second part has 2 digits, 7 and 5 respectively.Calculate Digit Verification of CAS Registry Number 3665-75:
(6*3)+(5*6)+(4*6)+(3*5)+(2*7)+(1*5)=106
106 % 10 = 6
So 3665-75-6 is a valid CAS Registry Number.
