22664-15-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 22664-15-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,6,6 and 4 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 22664-15:
(7*2)+(6*2)+(5*6)+(4*6)+(3*4)+(2*1)+(1*5)=99
99 % 10 = 9
So 22664-15-9 is a valid CAS Registry Number.
