DuPhos and BPE Ligands: Highly Efficient Privileged Ligands

Check Digit Verification of cas no

The CAS Registry Mumber 528565-79-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,2,8,5,6 and 5 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 528565-79:
(8*5)+(7*2)+(6*8)+(5*5)+(4*6)+(3*5)+(2*7)+(1*9)=189
189 % 10 = 9
So 528565-79-9 is a valid CAS Registry Number.
