4358-26-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4358-26-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,5 and 8 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 4358-26:
(6*4)+(5*3)+(4*5)+(3*8)+(2*2)+(1*6)=93
93 % 10 = 3
So 4358-26-3 is a valid CAS Registry Number.
