7740-66-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 7740-66-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,4 and 0 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 7740-66:
(6*7)+(5*7)+(4*4)+(3*0)+(2*6)+(1*6)=111
111 % 10 = 1
So 7740-66-1 is a valid CAS Registry Number.
