6665-77-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 6665-77-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,6 and 5 respectively; the second part has 2 digits, 7 and 7 respectively.Calculate Digit Verification of CAS Registry Number 6665-77:
(6*6)+(5*6)+(4*6)+(3*5)+(2*7)+(1*7)=126
126 % 10 = 6
So 6665-77-6 is a valid CAS Registry Number.
