114247-53-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 114247-53-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,4,2,4 and 7 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 114247-53:
(8*1)+(7*1)+(6*4)+(5*2)+(4*4)+(3*7)+(2*5)+(1*3)=99
99 % 10 = 9
So 114247-53-9 is a valid CAS Registry Number.
