565220-29-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 565220-29-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,6,5,2,2 and 0 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 565220-29:
(8*5)+(7*6)+(6*5)+(5*2)+(4*2)+(3*0)+(2*2)+(1*9)=143
143 % 10 = 3
So 565220-29-3 is a valid CAS Registry Number.
