5923-69-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5923-69-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,9,2 and 3 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 5923-69:
(6*5)+(5*9)+(4*2)+(3*3)+(2*6)+(1*9)=113
113 % 10 = 3
So 5923-69-3 is a valid CAS Registry Number.
