223547-66-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 223547-66-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,3,5,4 and 7 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 223547-66:
(8*2)+(7*2)+(6*3)+(5*5)+(4*4)+(3*7)+(2*6)+(1*6)=128
128 % 10 = 8
So 223547-66-8 is a valid CAS Registry Number.
