943-40-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 943-40-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,4 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 943-40:
(5*9)+(4*4)+(3*3)+(2*4)+(1*0)=78
78 % 10 = 8
So 943-40-8 is a valid CAS Registry Number.
