111455-87-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 111455-87-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,4,5 and 5 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 111455-87:
(8*1)+(7*1)+(6*1)+(5*4)+(4*5)+(3*5)+(2*8)+(1*7)=99
99 % 10 = 9
So 111455-87-9 is a valid CAS Registry Number.
