5765-41-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5765-41-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,7,6 and 5 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 5765-41:
(6*5)+(5*7)+(4*6)+(3*5)+(2*4)+(1*1)=113
113 % 10 = 3
So 5765-41-3 is a valid CAS Registry Number.
