1280228-22-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1280228-22-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,0,2,2 and 8 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1280228-22:
(9*1)+(8*2)+(7*8)+(6*0)+(5*2)+(4*2)+(3*8)+(2*2)+(1*2)=129
129 % 10 = 9
So 1280228-22-9 is a valid CAS Registry Number.
