140848-53-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 140848-53-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,8,4 and 8 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 140848-53:
(8*1)+(7*4)+(6*0)+(5*8)+(4*4)+(3*8)+(2*5)+(1*3)=129
129 % 10 = 9
So 140848-53-9 is a valid CAS Registry Number.
