7764-45-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7764-45-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,6 and 4 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 7764-45:
(6*7)+(5*7)+(4*6)+(3*4)+(2*4)+(1*5)=126
126 % 10 = 6
So 7764-45-6 is a valid CAS Registry Number.
