1028264-28-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1028264-28-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,8,2,6 and 4 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1028264-28:
(9*1)+(8*0)+(7*2)+(6*8)+(5*2)+(4*6)+(3*4)+(2*2)+(1*8)=129
129 % 10 = 9
So 1028264-28-9 is a valid CAS Registry Number.
