1228449-87-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1228449-87-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,8,4,4 and 9 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1228449-87:
(9*1)+(8*2)+(7*2)+(6*8)+(5*4)+(4*4)+(3*9)+(2*8)+(1*7)=173
173 % 10 = 3
So 1228449-87-3 is a valid CAS Registry Number.
