220436-96-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 220436-96-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,4,3 and 6 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 220436-96:
(8*2)+(7*2)+(6*0)+(5*4)+(4*3)+(3*6)+(2*9)+(1*6)=104
104 % 10 = 4
So 220436-96-4 is a valid CAS Registry Number.
