1280228-19-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1280228-19-4 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, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1280228-19:
(9*1)+(8*2)+(7*8)+(6*0)+(5*2)+(4*2)+(3*8)+(2*1)+(1*9)=134
134 % 10 = 4
So 1280228-19-4 is a valid CAS Registry Number.
